उत्तर
Solar photovoltaic cells convert the solar radiation energy directly into electrical energy.
Explanation:
Solar photovoltaic cell converts the solar radiation energy directly into electrical energy. This is called solar photovoltaic effect. The electrical energy generated through this energy transformation process is DC in nature. These solar cells are made of a special type of material called semiconductor (e.g. silicon).
