Solar cells (photovoltaic devices) generate electricity because they are made of silicon that:
ABurns sunlight to heat water into steam
BStores chemical energy for later release
CConverts sunlight directly into electricity
DConcentrates wind power onto a turbine
Answer & Solution
Correct answer: C. Converts sunlight directly into electricity
1. A solar cell is a silicon photovoltaic device.
2. It converts sunlight directly into electricity without fuel, gases or waste.
3. Heating water to steam describes a solar thermal plant, not a solar cell, so option A is a trap.
4. Hence the answer is C.
