The following graph depicts the I-V characteristics of which instrument?

The following graph depicts the I-V characteristics of which instrument? Correct Answer Solar Cell

The generation of EMF by a solar cell is due to three basic processes: generation of electron-hole pair, separation of electrons and holes and collection of electrons by the front contact. The p-side becomes positive and the n-side becomes negative giving rise to photo voltage. The I-V characteristics of the solar cell are drawn in the fourth quadrant of the coordinate axis because a solar cell does not draw current but supplies the same to the load.
