Question

Describe the working principle of photovoltaic solar cell

Answer 1

conversion of light energy in electrical energy is based on a phenomenon called photovoltic effect when semiconductor materials are exposed to light the sum of the photons of light rays are absorbed by the semiconductor crystal which courses are significant number of free electrons in the Crystal

Answer 2

conversion of light energy in electrical energy is based on a phenomenon called photovoltic effect when semiconductor material are exposed to light the some of the photons of light rays are absorbed by the semiconductor crystals which causes a significant number of free electrons in the crystal
