Which element is used in solar cells?(a) Carbon (b) Silicon (c) Phosphorus (d) Sulpher

(b) Silicon

Explanation

A solar cell is an electrical device that converts solar or light energy into electrical energy.

Solar cells or photovoltaic cells (PVs) are made of silicon, which is a semi-conductor. It has the ability to harvest sunlight and then transform it into usable electricity.

The reason for using "silicon" in solar cells is its ability to resist a very high temperature and current, and its maximum operating temperature is 150℃. Silicon is a semiconductor material that is an insulator at absolute zero temperature (0K). But, it conducts electricity under certain conditions, which is when the temperature starts increasing.
