उत्तर
Solar Photovoltaic cell
Explanation:
The Solar Photovoltaic cell differs in that it turns sunlight directly into electricity using the photovoltaic effect. In contrast, the other options—electricity generation using wind energy, hydroelectric power plant, and solar thermal power plant—require mechanical or thermal energy conversion operations before producing electricity.
