The development of solar panels can be traced back to the 19th century, where scientists and inventors began experimenting with the conversion of sunlight into electricity. However, it wasn’t until the mid-20th century that the first practical solar cells were created, thanks to the work of several researchers in the United States.
One of the pioneers in the field of solar energy was Russell Ohl, an American physicist who discovered the p-n junction, a key component of modern solar cells, in 1939. Ohl’s discovery allowed for the efficient conversion of sunlight into electricity, laying the foundation for the development of modern solar panels.
Another important contributor to the development of solar energy was Daryl Chapin, an American physicist who, along with his colleagues Calvin Fuller and Gerald Pearson, created the first practical solar cell in 1954. The three scientists were working at Bell Laboratories, a research facility owned by the American telecommunications company AT&T, when they developed the first silicon photovoltaic (PV) cell, which was capable of producing enough electricity to power small electronic devices.
While the earliest solar cells were expensive and inefficient, they paved the way for further research and development in the field of solar energy. In the following decades, scientists and engineers around the world worked to improve the efficiency of solar cells and reduce their cost, ultimately leading to the widespread adoption of solar energy as a viable alternative to traditional fossil fuels.
In the United Kingdom, solar energy has become an increasingly important source of renewable energy in recent years, with the government setting a target of generating 40% of the country’s electricity from renewable sources by 2030. While the UK has historically lagged behind other countries in terms of solar energy adoption, the falling cost of solar panels and the introduction of government subsidies have made solar power more accessible to homeowners and businesses.
One of the key figures in the UK’s solar energy industry is Jeremy Leggett, a British entrepreneur and environmentalist who founded the solar energy company Solarcentury in 1998. Leggett’s company has been involved in the installation of solar panels on a wide range of buildings, from homes and schools to commercial and industrial buildings.
In addition to Solarcentury, there are a number of other companies in the UK that are involved in the production and installation of solar panels, including SunPower, SolarEdge, and Suntech. These companies are responsible for developing new technologies and improving the efficiency of solar panels, making solar energy an increasingly viable alternative to traditional sources of electricity.
Overall, the development of solar panels has been a collaborative effort by scientists and engineers around the world, with contributions from individuals in the United States, Europe, and Asia. While the earliest solar cells were inefficient and expensive, the ongoing efforts of researchers and companies in the field of solar energy have made solar power a viable and increasingly important source of renewable energy for countries around the world, including the United Kingdom.
