The photoelectric cell, also known as a solar cell or photovoltaic cell, was invented in 1839 by French physicist Edmond Becquerel. Becquerel discovered the photovoltaic effect while experimenting with an electrolytic cell made up of two metal electrodes submerged in a conducting solution. He noticed that when the cell was exposed to light, it produced an electric current. < p>Today, photoelectric cells are widely used in solar panels to convert sunlight into electricity. They are a key component of renewable energy systems and play a crucial role in reducing our reliance on fossil fuels. < p>Photoelectric cells work by absorbing photons from the sun and using them to excite electrons in the cell's semiconductor material. This creates an electric current that can be harnessed and used as a source of power. < p>If you are interested in learning more about the history of photoelectric cells and their applications, there are many resources available online. Websites such as < a href="https://www.energy.gov/eere/solar/how-do-photovoltaics-work" >energy.gov< /a> offer detailed explanations of how photoelectric cells work and their impact on the environment. < p>Additionally, you can explore the latest advancements in solar technology by visiting websites like < a href="https://www.nrel.gov/research/re-photovoltaics.html" >nrel.gov< /a>.
