Question

Why is silicon preferred for making solar cell 0?

Answer 1

Answer:

Solar cell means when exposed to light, can generate and support an electric current without being attached to any external voltage source. And GaAS and Si are the semiconductors and preffered so. This is because the max intensity of electrons from sunlight have energy gap of around 1.5 ev.

Answer 2

Answer:

because silicon is a semi conductor...when sunlight falls on the surface of solar cell ,it make the loosely held electrons in the silicon atomsbmove due to which a currents begins to flow.

hope it helps.
