उत्तर
- The figure is related to schematic diagram of the solar thermal power plant.
- Many reflectors reflect and concentrate solar radiation on absorbers.
- Thermal energy is first created from solar radiation's energy. Then, using that thermal energy, a turbine generator system is operated to produce electricity.
- Solar photovoltaic cells immediately transform the energy of solar radiation into electrical energy. The solar photovoltaic effect is what causes this. This energy transfer process results in the creation of DC electrical energy.
