Question

Why do solar cells have a great future?

• A. They provide a clean source of energy.
• B. Supply of energy from sun is unlimited.
• C. The cost of conventional sources of energy is rising while cost of solar cells is reducing.
• D. All of the above.

Answer 1

Answer: (D)

All of the above.

Solar cell produces pure electricity with no waste products and is environment friendly.

Solar energy is unlimited, so solar cells have the ability to produce enormous electrical energy.

With improvement in manufacturing technologies and use of ICs, cost of solar cells is reducing. However, with depletion of natural resources conventional sources of energy are getting costlier.
