Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:Photovoltaic cells are often made up of crystalline silicon.
Statement II:Photovoltaic cells are also made up of inexpensive amorphous silicon, which is like ordinary glass and has no crystalline properties.
ABoth Statement I and Statement II are correct ✓ Correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect
DStatement I is incorrect but Statement II is correct
Correct answer: (A) Both Statement I and Statement II are correct
Explanation
Photovoltaic cells are commonly built from crystalline silicon that converts sunlight to electricity.
Statement 1 describing crystalline silicon cells is accurate.
Cheaper cells also use amorphous silicon, a non crystalline form resembling ordinary glass.
Statement 2 about inexpensive amorphous silicon without crystalline structure is also true.
Both forms work through the photovoltaic effect but differ in cost and efficiency.
Amorphous silicon films use far less material, though crystalline cells convert light more efficiently.
