Light energy produces the only voltage in a solar cell. (a)-true(t) (b)- false(f)

True

Explanation:

The fundamental steps involved in the operation of a solar cell are as follows:

Light is incident on the solar cell and this light energy is absorbed by the solar cell.The absorbed energy results in the movement of the electron inside the cell which constitutes the electric current in the cell.Electric current flows and electricity is produced.Hence,in solar cell the light energy is responsible for the only voltage in the cell.
