How Do Photocells Work
A photocell (photoconductive or photovoltaic) is an electrical device that connects and communicates with a transformer. It is a sensor/ resistor that convert light into electricity. When light falls, it transmits energy into the semiconductor part of the cell. Photocell Suppliers Dubai : SPPE What is photocell made up of? It is made of two types of semiconductors because, when it is connected to a battery; it conducts a little electric current; called “n” and “p.” The n-type semiconductor is so named because some of its atoms have extra electrons, which have a negative charge. Ap-type semiconductor: some of its atoms have fewer electrons. Working of Photocell: Photocell sensors work like a timer switch powering light fixtures off and on automatically during a set time. The production of electricity in it begins where the two types of semiconductors are joined together. It is called the p-n junction .When the sun shines on it, its photons get activ
