SSC GD 2023 PYQ — Question 27

The correct answer is option 4 i.e. It has no moving parts.

• Solar cells, also known as photovoltaic (PV) cells, are semiconductor devices that convert sunlight directly into electricity through the photovoltaic effect. 
• The absence of moving parts reduces the likelihood of mechanical failures, making solar cells a reliable and low-risk technology for electricity generation.
• The lack of moving parts contributes to the durability of solar cells.
