A solar panel is a device that absorbs sunlight and converts solar radiation directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. Compared with ordinary batteries and rechargeable batteries, solar batteries are more energy-saving and environmentally friendly.
Materials that can produce photovoltaic effects include monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, indium copper selenide, etc., and their power generation principles are basically the same. The main material of most solar panels is silicon. P-type crystalline silicon can be doped with phosphorus to obtain N-type silicon and form a P-N junction. When the light hits the surface of the solar cell, part of the photons are absorbed by the silicon material; the energy of the photons is transferred to the silicon atoms, causing the electrons to transition and become free electrons that accumulate on both sides of the P-N junction to form a potential difference. When the external circuit is turned on, under the action of this voltage, a current will flow through the external circuit and generate a certain output power.
