Photovoltaic support blocking

Photovoltaics

A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photoelectric effect. The first solar cell was constructed by Charles Fritts (Perlin 1999) in the 1880s. In 1931 a German engineer, Dr. Bruno Lange (Popular Science 1931), developed a photo cell using silver selenide in place of copper oxide.
