MODEL RELEASED. Solar panel construction. Worker building a solar panel using circular photovoltaic,or solar,cells. Completed panels are seen behind her. Photovoltaic cells are made of a semiconductor material such as silicon or gallium arsenide. The electrons in the semiconductor are loosely bound to their atoms and can be liberated by the addition of energy. The electrons released when light energy hits the panel will be collected by the wires that run over the surface of each cell and used to make an electric current | |
