Question
Simran is trying to make a solar cell. She stacks many individual cells together. What material should she use?
- Diodes
- Electro-metals
- Semiconductors
- Solarductors
Hint:
The semiconductors are good conductors of electric energy than the insulators.
The correct answer is: Semiconductors
When Simran stacks many individual cells together, she should use a semiconductor to conduct the electricity.
- The solar panels are made up of photovoltaic cells.
- The electricity is drawn by using a semiconductor.
- The light from the sun is reflected or refracted to generate electric energy.
- The semiconductor conducts better than the insulators.
