What solar panels are installed on community windows?

Solar panels (also called solar cell modules) are an assembly of several solar cells assembled together. They are the core part of the solar power generation system and the most important part of the solar power generation system. The principle of power generation is that sunlight shines on the p-n junction of the semiconductor to form a new hole-electron pair. Under the action of the electric field of the p-n junction, holes flow from the p region to the n region and the electrons. circulates from region n to region p. Once the circuit is connected, a new hole-electron pair is formed.
