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