The solar panel is not our traditional battery. No matter its shape and color, the power generation principle is very different from the traditional battery.
Solar panels, sometimes called photovoltaic cells, collect solar energy in the form of sunlight and convert it into electricity. Single solar cells cannot be used as power supply directly. As a power supply, a number of individual solar cells must be connected in series or parallel and tightly packaged into solar panels, which can be used to supply power for families or enterprises. These panels can be used to supplement the power of buildings or provide power in remote areas.
The solar panel structure is mainly made of surface material (PET/ETFE/glass)+EVA+solar cell+EVA+back material (PET, TPT, PCB). Generally, the surface material is hard and the back material is soft. The surface material generally has the requirement of high transmittance, which can project the sunlight into the solar cell inside the solar energy, and let the sunlight shine on the semiconductor p-n junction to form a new hole-electron pair. Under the effect of the electric field of the p-n junction, the hole flows from the p-region to the n-region, and the electron flows from the n-region to the p-region, and the current is formed after the circuit is connected. This is the working principle of the photoelectric effect solar panel. The back material is generally used to protect the back of the solar cell inside.
There are many kinds of batteries in the traditional sense, including lithium batteries, alkaline batteries, carbon-zinc batteries, silver oxide batteries, nickel-cadmium batteries, nickel-hydrogen batteries, 12V batteries, and 22V batteries. Their names and properties vary according to the different substances in them. In a narrow sense, a battery is a device that converts its stored chemical energy into electrical energy; In a broad sense, a battery is a device that converts “pre stored” energy into external power. However, solar panels can only generate electricity in the sun. If it is rainy, they cannot generate electricity or store electricity.
