The working of solar cell and LED are reverse to each other.
Explanation:
We forward bias the LED. Then electron and holes combine each other due to which light is produced and it begins to glow. While in solar cell light is thrown on the P-N junction due to which an electron hole pair is produced. Another thing is the electric field in the depletion region of solar cell helps in establishing the current in solar cells.
