When were Photovoltaic Cells Invented?
The Invention of Photovoltaic Cells
The invention of photovoltaic cells, also known as solar cells, can be traced back to the 19th century. In 1839, a French physicist named Alexandre-Edmond Becquerel discovered the photovoltaic effect while experimenting with an electrolytic cell made up of two metal electrodes.The Development of Photovoltaic Technology
Building upon Becquerel’s discovery, the first practical photovoltaic cell was developed in 1954 by Bell Laboratories. This early model was made of silicon and was able to convert sunlight into electricity with an efficiency of around 6%. Over the years, advancements in photovoltaic technology have led to increased efficiency and decreased costs, making solar cells a viable and sustainable energy source.The Impact of Photovoltaic Cells
Photovoltaic cells have had a significant impact on the world’s energy landscape. They have provided a clean and renewable alternative to fossil fuels, reducing greenhouse gas emissions and contributing to the fight against climate change. Solar energy has become more accessible to the general public, with many homeowners and businesses investing in solar panels to power their properties.
