Materials used in solar cells must possess a band gap close to 1.5 ev to optimize light absorption and electrical efficiency. Commonly used materials are- Silicon. GaAs. CdTe. Must have band gap from 1ev to 1.8ev. It must have high optical absorption. It must have high electrical conductivity.
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.
The main types of solar cells are crystalline silicon (which includes monocrystalline and polycrystalline, thin-film (using materials like CdTe and CIGS), and emerging technologies like perovskite and organic cells. Each type has its own strengths and is used in different ways depending on the application.
Solar cells can be made of a single layer of light-absorbing material (single-junction) or use multiple physical configurations (multi-junctions) to take advantage of various absorption and charge separation mechanisms. Solar cells can be classified into first, second and third generation cells.
Other materials used for the construction of photovoltaic cells are polycrystalline thin films such as copper indium diselenide, cadmium telluride, and gallium arsenide. A number of the earliest photovoltaic (PV) devices have been manufactured using silicon as the solar cell material and it is still the most popular material for solar cells today.
The overwhelming majority of solar cells are fabricated from silicon —with increasing efficiency and lowering cost as the materials range from amorphous (noncrystalline) to polycrystalline to crystalline (single crystal) silicon forms.
