What light generates electricity for solar panels

Solar panels can also use lights to generate electricity. As long as the effective light waves meet the generation conditions of the PN junction of the panels, they can generate electricity. Datang Photovoltaic Energy will give you a detailed explanation of the energy production principle of solar panels. Sunlight shines on the p-n junction of the semiconductor, forming new hole-electron pairs. Under the action of the electric field of the p-n junction, holes flow from region n to region p and electrons flow from region p to region n. the circuit is turned on, a current is formed. This is how photovoltaic solar cells work. Solar power generation methods There are two solar power generation methods: one is the light-heat-electricity conversion method and the other is the direct light-electricity conversion method.1. The light-heat-electricity conversion method uses thermal energy generated by solar radiation to produce electricity. Generally, a solar collector converts the absorbed thermal energy into steam as the working fluid and then drives a steam turbine to produce electricity. The first process is a light-heat conversion process; the second process is a heat-electricity conversion process, which is the same as ordinary thermal power generation. The disadvantages of solar thermal power generation are that its efficiency is very low and its cost is high. Its investment is estimated to be at least higher than that of ordinary thermal power generation. Power plants are therefore 5 to 10 times more expensive. They can therefore only be used on a small scale on special occasions. is not economically feasible and cannot compete with power plants tordinary hermic or nuclear weapons. 2. Direct light-to-electricity conversion method This method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device for converting light into electricity is the solar cell. A solar cell is a device that directly converts solar energy into electrical energy through the photovoltaic effect. When the sun shines on the photodiode, the photodiode converts light energy from the sun into electrical energy, producing current. When many batteries are connected in series or parallel, a solar cell array with relatively large output power can be formed. Solar cells are a promising new energy source with three major advantages: Solar cells have a long lifespan and can be invested once and used for a long time.period as long as the sun exists, they are different from the production of thermal energy; and nuclear energy production. In comparison, solar cells do not cause environmental pollution; Solar cells can be used in large, medium and small power plants, ranging from medium-sized one million kilowatt power plants to small solar batteries for a household. This is unmatched by other energy sources. If you have any questions about solar panels, welcome to Datang Photovoltaic Energy to learn, http://www.datangpv.com
