Solar panels have become increasingly popular in recent years as individuals and businesses alike look for more sustainable sources of energy. But who invented solar panels, and how did they become the technological marvels they are today?
The earliest version of a solar panel can be traced back to 1839 when French physicist Alexandre-Edmond Becquerel discovered the photovoltaic effect. This phenomenon occurs when certain materials generate an electric current when exposed to light. However, it wasn’t until the mid-20th century that solar panels began to take shape as we know them today.
In 1954, American researchers Daryl Chapin, Calvin Fuller, and Gerald Pearson invented the first practical silicon solar cell. This cell was capable of converting enough sunlight into electricity to power small electrical devices. The invention was a significant breakthrough in solar technology, and it marked the beginning of the modern era of solar power.
However, it wasn’t until the 1970s that solar panels began to gain widespread popularity. The oil crisis of 1973 sparked interest in alternative energy sources, and solar panels were one of the most promising options. Governments worldwide began to invest heavily in solar power research and development, and the industry began to take off.
But what about the United Kingdom? Who played a role in the development of solar panels there?
While the United Kingdom may not be a major producer of solar panels, it has played an important role in advancing solar technology. One of the key figures in this regard is Professor Anthony E. Kelly, a physicist who made significant contributions to the field of photovoltaics.
Kelly was born in London in 1926 and studied physics at Imperial College London. After completing his Ph.D. in 1953, he joined the Royal Radar Establishment in Malvern, where he worked on various projects related to semiconductor technology.
In the early 1960s, Kelly became interested in the potential of solar energy. He recognized that solar panels could provide a clean and renewable source of electricity, but the technology was still in its infancy. To advance the field, Kelly founded the Solar Energy Research Laboratory (SERL) at the University of Surrey in 1972.
SERL was one of the first research facilities in the United Kingdom dedicated to solar energy. Over the years, Kelly and his team made numerous breakthroughs in photovoltaic technology, including developing new materials for solar cells and improving their efficiency.
One of Kelly’s most significant contributions to solar technology was his development of the “n-p-n” solar cell. This type of cell was more efficient than previous designs, and it helped pave the way for the widespread use of solar panels.
In addition to his work at SERL, Kelly was also a founding member of the European Photovoltaic Solar Energy Conference and Exhibition. This event, which is still held annually, brings together researchers, engineers, and industry professionals from around the world to share their latest findings in solar technology.
In conclusion, while solar panels may not have been invented in the United Kingdom, the country has played an important role in advancing the technology. Professor Anthony E. Kelly, in particular, was a key figure in the development of photovoltaic technology, and his contributions continue to shape the industry to this day. As the world looks for more sustainable sources of energy, it is likely that solar panels will continue to play an increasingly important role in meeting our energy needs.
