How Photovoltaic Solar Panels Work

Download to read offline

Photovoltaic solar panels work by allowing particles of light known as photons to generate electricity by knocking electrons free from atoms. Each solar panel is comprised of a linked series of photovoltaic cells made of two slices of silicon, or another semi-conducting material.

  3. 3. 3 ESTABLISHING THE ELECTRIC FIELD Manufacturers of solar photovoltaic panels infuse the silicon in each half of the sandwich with other materials (boron and phosphorous), which give each side either a positive or a negative charge. This establishes an electric field within the junction between the two slices, which pushes electrons out of the junction once the sunlight has knocked them free. CONDUCTIVE PLATES Solar panels have metal conductive plates fitted to the sides of each cell. These plates turn the electrons that have been knocked free into usable electric power, which is then sent to wires which can be connected to the grid or any other form of electrical storage. Each solar panel is comprised of a linked series of photovoltaic cells made of two slices of silicon, or another semi-conducting material.
  4. 4. New technologies are being developed that have the potential to make solar photovoltaic energy an affordable and efficient alternative to fossil fuels. You can learn more about these by visiting the blog of Duncan Clark, Nextgen Nano’s Director of Operations. DUNCAN CLARK
