Crystalline Silicon Photovoltaics Research
In a silicon solar cell, a layer of silicon absorbs light, which excites charged particles called electrons. When the electrons move, they create an electric current. In a solar cell, the silicon absorber is attached to other materials, which allows electric current to flow through the absorber layer into the metal contacts and be collected as ...
