Hint: Use the concept of the solar cell and working of it. Use the proper principle for working of a solar cell and then match one by one from the given option to find the correct answer. Use a different form of solar cell.

Complete step by step solution:
A solar cell which is also known as a photovoltaic cell or PV cell is defined as an electrical device which converts the light energy to electrical energy through the photovoltaic effect (principle of working of solar cell). A solar cell can be treated as a p-n junction diode. A form of photoelectric cell is the solar cells.
Individual solar cells combine to form solar panels. A maximum open-circuit voltage of approximately $0.5$ to $0.6$ volts can be produced by the common single silicon solar cell. Individually, this isn’t much, but, when combined into a large solar panel, considerable amounts of renewable energy can be generated. The materials which we generally used for this solar cell must have a band gap close to $1.5\text{ eV}$, high optical absorption, high electrical conductivity. Generally, we use GaAs as solar cell material.
The advantages of solar cell are as follows,
It contributes to a pollution free environment.
Solar cells have longer life cycles.
Maintenance of solar cells is less or nothing.
The disadvantages of solar cell are as follows,
Installation cost is very high.
Efficiency is very less.

Hence, from the above explanation it is observed that the correct answer is photovoltaic effect and the correct option is A.

Note:Make sure about the principle of solar cell and eliminate the other options carefully. Go through the working of a solar cell properly to know the exact and accurate answer. Avoid Silly mistakes to tick the correct answer.
