Hello candidate,

I am sorry to inform you but due to a limitation on the number of answering modes available on this platform is not possible for me to draw an equivalent circuit for you in order to explain the solar cell with its working explanation of of an electrical circuit.

But, a solar cell is generally functioning on the principle of charge Carriers and charge inductors which get transmitted from the lower energy band to the higher energy mint in the form of electrons which involves both the principle of photoelectric effect and semiconductor induction on the application of UV rays.

Hope you found it helpful!!
