Semiconductors

Poorly conductive materials doped with impurities, which act to increase electrical conductivity to a level intermediate between non-conductors and conductors. Bonded together in photovoltaic cells, they can generate an electrical current.

Solar energy

Solar radiation that reaches the Earth’s surface is potentially available as an energy resource as direct solar energy using photovoltaic cells.
