Simplified version.
There's an internal wall that lets electrons through easier going one way than the other. The Sun shines on one side of the wall and knocks electrons over the wall. But they can't get back.
So an electric charge builds up. Wires take the electrons away as electricity.

It is a semiconductor device that is made to optimize the photoelectric effect, where energy from light is changed into electrical energy. It is basically an array of photo diodes which work the opposite way as Light Emitting Diodes (LEDs). The LED takes electricity and makes light, while the photocell takes light and makes electricity.

there is a chemical,or film, that is inside the solar panel. When the sun hits it, and heats it, the heat is converted into electrical current.
The electrical current is stored in a battery that, depending on your inverter, can give you either ac or dc power
this is the easy explanation.
