Thin-film cells are obtained by depositing several layers of PV material on a base. The different types of PV cells depend on the nature and characteristics of the materials used. The most common types of solar panels use some kind of crystalline silicon (Si) solar cell. This material is cut into very thin disc-shaped sheets, monocrystalline or ...
Numerical Simulation of Solar Cells and Solar Cell
different semiconductors are used to form the solar cell absorber (photon collecting area), the electron extracting area and the hole extracting area of th e solar cell. Ideally, the excess carriers of the solar cell absorber (electrons and holes) should be selectively attracted/repelled towards the contacts, see Fig. 2.
