Photovoltaic effect

The photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light. It is a physical phenomenon. The photovoltaic effect is closely related to the photoelectric effect. For both phenomena, light is absorbed, causing excitation of an electron or other charge carrier to a higher-energy state. The main distinction is that the term photoelect…

Measuring and estimating the temperature of photovoltaic modules

1. Introduction Module temperature is an important factor that influences the power produced by a photovoltaic system (Ye et al., 2013, Lobera and Valkealahti, 2013).Typically, a crystalline silicon module loses about 4% of its power output for every 10 C raise in module temperature. C raise in module temperature.
