Semiconductor materials are used to make PV cells. A semiconductor is a substance that has both insulator as well as conductor characteristics. At very low temperatures, semiconductors behave as insulators, and their conductivity increases as the temperature rises. At normal temperatures, a. The photovoltaic effectis the basic physical mechanism by which a PV cell converts light into electricity (see figure 3). When a material absorbs photons with energy above a certain threshold, the photovoltaic effect causes electrons to move within the material. A photon is. PV cells can be produced from a variety of semiconductor materials, though crystalline silicon is by far the most common.
