| Video Discription | This video is about how do solar cells work and how do solar panels work. Q: How do solar cells work? Ans: Solar cells work due to P-N Junction. Solar cells are made up from two layers. The upper layer of the solar cell is made up of Silicon and some atoms of Phosphorus. The lower layer of the Solar Cell is made of Silicon and some atoms of Boron. The upper layer is known as N-region, because it contains higher concentration of electrons. While the lower region is known as P-region, because it contains higher concentration of wholes. In physics, we say that the upper layer has N-type doping while the lower layer has P-type doping. When these two doped regions are combined together, they form a depletion region. Hence, some electrons from the N-region move to the P-region. As a result, negative charge appears on the boundary of N-region while positive charge appears on the boundary of P-region. Thus electric field is formed between N-region and P-region. This electric field provides the necessary force to drive electrons from the N-region to the P-region if conducting path is provided. (How Does Solar Energy Work?
