WebJul 11, 2024 · Photoresistor is also known as Light Dependent Resistor. It us a electronics component whose resistivity is a function of the incident electromagnetic radiation. Hence it is a light sensitive device. So, it is called photoconductive cells, photoconductor or simply photocells. It is constructed by a semiconductor material with high resistance. WebFigure 21.9 A solar cell is an example of a photovoltaic cell. As light strikes the cell, the cell absorbs the energy of the photons. If this energy exceeds the binding energy of the electrons, then electrons will be forced to move in the cell, thereby producing a current. This current may be used for a variety of purposes.
