Solution
The correct option is D All of the above
Photovoltaic cells are used in trapping solar energy. These are made of semiconductors that can lose the electrons when exposed to the sunlight to generate the electric current. The semiconductor material used can be silicon, gallium arsenide, cadmium telluride. Silicon is the most preferred because of its uniform crystalline structure. Cadmium Telluride provides a low-cost alternative that is also highly absorptive of solar energy. Gallium arsenide is used for its resistance to the harmful effects of the radiations. It is generally used for space photovoltaic cells.Hence, the correct answer is 'All of the above'
