A single solar cell can produce only a small amount of electricity. In those cases where more electrical power is needed, a large number of solar cells are joined together in series. This group of solar cells is called a 'solar cell panel'. Thus, a solar cell panel consists of a large number of solar cells joined together in a definite pattern.1. A potential difference of about ................ is generated between the top and bottom surface of a solar cell.a. 0.5 Vb. 0.05 Vc. 0.9 Vd. None of these2.
