Question

Solar cell is based on the principle of
A) Formation of electron-hole pairs with heating.
B) Formation of electron-hole pairs with potential.
C) Formation of electron-hole pairs with incident light.
D) All of these​

Answer 1

Answer:

all of thwee because it is based on the principal of photovoltaic light

Answer 2

Option C) is the correct answer.

• These solar cells work on the principle of photovoltaic effect.
• When the sunlight incident the solar panels, these panels absorb the light energy.
• These solar panels are made up of p-type and n-type semiconductors.
• When the incident light falls on the p-type and n-type silicon semiconductors, recombination takes place.
• Due to recombination, the electrons-hole pair formation takes place, which will covert the light energy into electric energy.
• Therefore, option c)  Formation of electron-hole pairs with incident light is the correct option.
