Correct option is D
A solar cell is a system of many units that uses the photovoltaic effect to directly transform light energy into electrical energy.
• Solar cells also known as photovoltaic cells, are produced using the photovoltaic effect.
• They convert the light of the sun into direct current (DC) electricity.
• Silicon is used for making solar cells.
• A solar panel, which is made up of silicon semiconductors is called a silicon solar panel.
• Silicon semiconductors are most popular because they have properties such as low weight volume ratio, extended life cycle, robustness and strength.
