question 14 of 25
why does the layer of glass in a solar cell need an antireflective coating?
a. to give the layer a negative charge
b. to give the layer a positive charge
c. to maximize the energy absorbed by the solar cell
d. to help the cell conduct the charge that is produced

Explanation:

Antireflective coating on the glass layer of a solar cell works by minimizing the reflection of light. When light is reflected less, more light can enter the solar cell. Since solar cells convert light energy into electrical energy, more light entering (less reflection) means more energy can be absorbed and converted. Options A and B about giving charge are not related to antireflective coating's function. Option D about conducting charge is also not the role of antireflective coating.

Answer:

C. To maximize the energy absorbed by the solar cell
