How Photovoltaic Cells Generate Electricity
The depletion region as explained previously with the diode is the area around the PN junction where the electrons from the N-type silicon, have diffused into the holes of the P-type material. When a photon of light is absorbed by one of these atoms in the N-Type silicon it will dislodge an electron, creating a free electron and a hole.

What is a Solar Cell? A Guide to Photovoltaic Cells
The photovoltaic effect is the underlying mechanism that allows solar cells to produce electricity, involving the movement of electrons between the cell''s p-type and n-type layers. Solar cells are the basic building blocks of photovoltaic systems, which can range from powering small electronic devices to large-scale utility-grade power plants.
The photovoltaic effect
In order to generate power, a voltage must be generated as well as a current. Voltage is generated in a solar cell by a process known as the "photovoltaic effect". The collection of light-generated carriers by the p-n junction causes a movement of electrons to the n-type side and holes to the p-type side of the junction. Under short circuit ...
