A photovoltaic cell is a p-n junction on a thin, flat wafer. A p-n junction is an intersection between adjacent layers of p-type and n-type semiconductor materials. As a p-n junction is illuminated, high-energy photons absorbed at the junction transfer their energy to electrons in the material, causing the electrons to move to a higher energy state. The electrons …
