Diagram the working of photo-voltaic cell:
Working:- Solar cell operates on principle of Photo-voltaic effect
Solar cell works in following steps: The solar cell is composed of a P-type semiconductor and an N-type semiconductor. When sun light (photon) is absorbed by the semiconductor material the cell produces two types, - A negatively charged electron and Positively charged holes are created due to photovoltaic effect. Negatively charged (-) electrons gather around the N-type semiconductor while Positively charged (+) electrons gather around the P-type semiconductor. When you connect loads such as a light bulb, electric current flows between the two electrodes.
