Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
Main types of PV cells that are made of silicon are: Mono-crystalline Silicon Cell; Ploy-crystalline Silicon Cell; Thin Film Silicon Cell; Crystalline Silicon PV Cell. Technology used for producing crystalline silicon is
Amorphous/thin film solar panels. At 7%, thin film solar panels are among the least efficient on the market but they are the cheapest option. They work well in low light, even moonlight, and are made from non-crystalline silicone that can be transferred in a thin film onto another material such as glass.
