Who discovered solar panel?
The history of solar panels can be traced back to the 19th century when French scientist Alexandre-Edmond Becquerel discovered the photovoltaic effect, which is the basic principle behind the operation of solar panels. In 1839, Becquerel discovered that certain materials, such as selenium, produced an electric current when exposed to light. This was the first step towards the development of solar cells, which are the building blocks of solar panels.
However, it wasn’t until the 20th century that the development of solar panels really took off. In the early 1900s, several scientists and engineers began experimenting with different materials and designs for solar cells. One of the most notable of these early pioneers was American inventor Charles Fritts, who created the first solar cell made of selenium in 1883.
It wasn’t until the 1950s that the first practical solar cell was developed. Researchers at Bell Labs in the United States created a solar cell with an efficiency of 6%, which was a significant improvement over previous designs. This breakthrough led to the development of the first commercial solar panels, which were used primarily in space applications.
In the decades that followed, the efficiency of solar cells continued to improve, and the cost of producing solar panels began to decrease. This led to the widespread adoption of solar panels in various applications, including residential and commercial power generation.
In conclusion, the discovery of solar panels is a result of the hard work and contributions of many scientists and engineers over the course of several decades. The discovery of photovoltaic effect by Alexandre-Edmond Becquerel in 1839 was the initial step and the invention of solar cells by Charles Fritts in 1883 and the practical solar cell by Bell Labs in the 1950s are some of the most notable milestones in the history of solar panel technology. Today, solar panels are a vital source of clean and renewable energy, and their use is expected to continue to grow in the future.
Life of Alexandre-Edmond Becquerel
Alexandre-Edmond Becquerel was a French physicist and one of the pioneers of the study of photovoltaics, the technology behind solar panels. He was born in Paris on December 15, 1820, and was the son of Antoine César Becquerel, a well-known scientist in his own right.
Becquerel began his scientific career studying the properties of light and electricity. In 1839, he discovered the photovoltaic effect, which is the basic principle behind the operation of solar cells and solar panels. He discovered that certain materials, such as selenium, produced an electric current when exposed to light. This was a significant breakthrough in the field of photovoltaics and laid the foundation for the development of solar cells and solar panels.
Throughout his career, Becquerel continued to study the properties of light and electricity, and he made many other important contributions to science. He was particularly interested in the phenomenon of fluorescence, and he discovered that certain materials, such as quinine, emitted light when exposed to ultraviolet light. This work laid the foundation for the study of luminescence and the development of modern light-emitting diodes (LEDs).
Becquerel was also a skilled experimentalist and was known for his meticulous and thorough approach to research. He published many papers on his work and was recognized by his peers for his contributions to science. He was elected to the French Academy of Sciences in 1857, and in 1875 he was awarded the Royal Society’s Rumford Medal in recognition of his work on the photovoltaic effect.
Becquerel died on October 18, 1891, in Paris. He was honored for his contributions to science, and his legacy continues to this day in the form of the Becquerel Prize, which is awarded annually by the European Commission for outstanding contributions to the field of photovoltaics.
Life of Charles Fritts
Charles Fritts was an American inventor and one of the pioneers of the development of solar cells, the building blocks of solar panels. He is credited with creating the first solar cell made of selenium in 1883, which marked an important step towards the practical use of solar energy.
Fritts was born in New York City in 1853 and began his career as an electrician. He was interested in the properties of light and electricity, and he began experimenting with different materials and designs for solar cells in the early 1880s. In 1883, he created the first solar cell made of selenium, which had an efficiency of less than 1%. While this was a relatively low efficiency compared to modern solar cells, Fritts’ invention was a significant breakthrough at the time and marked the first practical application of the photovoltaic effect.
Fritts continued to work on improving the efficiency of his solar cells and in 1888, he published a paper describing his latest design, which had an efficiency of about 4%. He also developed a process for producing large quantities of solar cells, which helped to make them more affordable.
Despite his pioneering work in the field of solar energy, Fritts did not receive much recognition during his lifetime. His work was largely overshadowed by the more well-known scientists and engineers of the time, such as Alexander Graham Bell and Thomas Edison. However, in recent years, Fritts has been acknowledged for his contributions to the field of photovoltaics and his role in the development of solar cells and solar panels.
Solar Power and Solar Panels in India
Solar power in India has grown significantly in recent years, making it one of the leading nations in the world in terms of installed solar capacity. The Indian government has set ambitious targets for the growth of solar power, and the country is well on its way to achieving those goals.
One of the main drivers of solar power in India is the country’s large and growing energy needs. India is the world’s third-largest energy consumer, and its energy consumption is expected to triple by 2040. This has led to a strong need for renewable energy sources, such as solar power, to help meet the country’s energy demands.
The Indian government has implemented a number of policies and programs to promote the growth of solar power.

Another challenge is the lack of access to education and training, which can limit the potential of the workforce.
Population as resource in India
Youth can be considered a valuable resource for a country, as they have the potential to contribute significantly to the development and growth of a nation. The youth population, defined as those aged 15-24, makes up a significant portion of the total population in many countries, and their active participation in society can have a positive impact on the economy, politics, and culture.
One of the key ways in which youth can contribute to a country’s development is through their participation in the workforce. Young people bring energy and new ideas to the workplace, and they can play a vital role in driving innovation and productivity. They also have the potential to fill skills gaps in the labor market, and can help to drive economic growth.
Additionally, youth can play an important role in shaping the political and social landscape of a country. They have the ability to bring fresh perspectives and new ideas to the table, and can play a key role in driving social change and progress. They also have the potential to be active and engaged citizens, and can help to promote democratic values and institutions.
Furthermore, youth can also contribute to the cultural and creative life of a country. They have a unique perspective on the world, and can bring new and exciting ideas to the arts, music, and literature. They can also play an important role in preserving and promoting the cultural heritage of a country.
However, it is important to note that in order for youth to fully realize their potential as a resource for a country, they must have access to quality education, training, and employment opportunities. They also require a supportive environment that encourages their participation in the workforce, politics, and cultural life of the country.
The population of India is the second-largest in the world, with over 1.3 billion people as of 2021. India is a diverse country with a wide range of ethnic and linguistic groups, and has a rapidly growing population that is projected to reach 1.5 billion by 2030.
One of the main drivers of India’s population growth is its high fertility rate. The total fertility rate in India is 2.3, which is higher than the replacement level of 2.1. This has led to a large youth population, with over 50% of the population being under the age of 25.
Another driver of India’s population growth is its relatively young age structure. The median age in India is 27, which is lower than the global median age of 30. This means that a larger share of the population is in the reproductive age group, which contributes to the high fertility rate.
The population of India is also highly urbanized, with over 31% of the population living in urban areas. This is expected to increase in the future, as the country’s urbanization rate is among the highest in the world.
However, the population growth in India also poses several challenges. The rapid population growth has put a strain on the country’s resources, and has led to issues such as overcrowding, pollution, and shortage of housing. Additionally, the population growth has led to increased competition for jobs, which can make it difficult for people to find employment.
The government of India has implemented several policies to address the population growth, such as the National Population Policy (2000) and the National Health Policy (2017). These policies aim to improve access to family planning services, education and healthcare, and to create awareness about the importance of smaller family sizes.
What is National Population Policy (2000)?

Relation of India with US, Russia, China and Pakistan
India, the world’s largest democracy and a rapidly emerging economy, has complex and multifaceted relations with the United States, Russia, and China, three of the world’s most powerful nations. These relationships are shaped by a combination of historical, economic, and strategic factors, and they have a significant impact on the regional and global balance of power.
India’s relationship with the United States is one of the most important and dynamic in the world. The two countries have a long history of cooperation and partnership, and the relationship has grown stronger in recent years, particularly in the areas of trade, defense, and counter-terrorism. The United States has also been a strong supporter of India’s rise as a global power and has played a key role in India’s integration into the global economy.
India’s relationship with Russia, on the other hand, has a historical and strategic dimension. Russia has been a long-term supplier of military equipment to India, and the two countries have also cooperated in the fields of energy, space, and civil nuclear energy. However, in recent years, India has been diversifying its defense imports and seeking to reduce its dependence on Russia.
China, which shares a long and disputed border with India, is a major economic and strategic rival of India. The two countries have had a number of disputes over territory and resources, and their relationship has been marked by mistrust and competition. However, in recent years, the two countries have also sought to improve relations and increase economic cooperation.
India and Pakistan’s relationship is one of the most complex and contentious in the world. The two countries have a long history of conflict, dating back to the partition of British India in 1947 and the subsequent formation of the two independent nations of India and Pakistan. The relationship has been marked by a number of disputes, including the ongoing Kashmir conflict, and has resulted in several wars and military standoffs.
One of the main issues that has contributed to the strained relationship between India and Pakistan is the ongoing dispute over the region of Kashmir. Both countries claim the region as their own, and the issue has led to several wars and military standoffs. The situation in Kashmir remains tense, with ongoing cross-border militancy and human rights violations reported on both sides.
Another major issue that has contributed to the strained relationship between India and Pakistan is the issue of terrorism. Both countries have accused each other of supporting and harboring terrorist groups, and have been involved in a number of terrorist attacks. The most notable of these was the 2008 Mumbai terrorist attacks, which were planned and executed by a Pakistan-based terrorist group.
Despite these challenges, there have been some efforts in recent years to improve relations between India and Pakistan. The two countries have engaged in a number of peace talks and diplomatic initiatives, including the ongoing backchannel dialogue. These efforts, however, have not yet resulted in a significant breakthrough in the relationship.
