How do PV modules convert sunlight into electricity?

Solar panels are made from thin layers of silicon, a semiconductor material that absorbs the suns rays and turns them into electricity. When photons from the sun hit the photovoltaic cells in a solar panel, electrons in the solar cell are knocked loose from their atom, allowing the electrons to flow freely. Solar cells force these electrons to flow in a certain direction along a wire, creating a current, which is then drawn off the cell to create electricity that powers your home or business.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
