A typical silicon PV cell is a thin wafer, usually square or rectangular wafers with dimensions 10cm × 10cm × 0.3mm, consisting of a very thin layer of phosphorous-doped (N-type) silicon on top of a thicker layer of boron-doped (p-type) silicon.
Materials presently used for photovoltaic solar cells include monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium selenide/sulfide. Many currently available solar cells are made from bulk materials that are cut into wafers between 180 to 240 micrometers thick that are then processed like other semiconductors.
While silicon wafers are commonly used in electronics and micromechanical devices, they also play a significant role in energy conservation and production. Silicon wafer suppliers often provide these materials to companies that manufacture solar panels.
Solar cells are the components that directly convert sunlight into electricity. They are made from silicon wafers and are typically encapsulated within a protective layer to ensure longevity.
