Solar Photovoltaic Cell Basics
Silicon . Silicon is, by far, the most common semiconductor material used in solar cells, representing approximately 95% of the modules sold today. It is also the second most abundant material on Earth (after oxygen) and the most common semiconductor used in computer chips. Crystalline silicon cells are made of silicon atoms connected to one …
The sunlight that powers solar panels also damages them.
A solar cell converts sunlight into electricity by using the energy from sunlight to "break away" negative charges, or electrons, in the silicon. The electrons are then collected as electricity .
The photovoltaic effect
This separation of charge creates an electric field at the junction which is in opposition to that already existing at the junction, thereby reducing the net electric field. Since the electric field represents a barrier to the flow of the forward bias diffusion current, the reduction of the electric field increases the diffusion current. A new ...
