Chapter 8, Problem 39R

To determine

To choose: The correct option.

Answer to Problem 39R

Option (C)

Explanation of Solution

Introduction:

The solar cell uses the solar energy to generate the electrical energy. The electrical energy generates due the movement of the electrons in the solar cell. The movement of the electron occurs due to the energy of the photon from the solar energy.

The solar cells does not produce pollution, so these are the pollution free medium of the energy.

The solar cells are made of the semiconductors. The semiconductors are very expensive, so the use of the solar cell for the electricity becomes expansive.

The solar cells use the solar energy to generate electricity, so these are the renewable source of the energy.

The solar cell covers large area due the big size of the solar panels, so solar cells requires more space to generate electricity.

If the cost of the solar cell become less than they would be more practical to use, so the option (C) is correct from the given option and other options are incorrect.

Conclusion:

Thus, the option correct option is (C).
