The composition and basic composition of solar panels, see which ones have you overlooked?

Solar cells, also known as "solar chips" or "photocells", are photoelectric semiconductor sheets that use sunlight to directly generate electricity. Single solar cells cannot be used directly as power sources. As a power source, a number of single solar cells must be connected in series, connected in parallel and tightly sealed into components. Solar panels (also called solar cell modules) are assembled by multiple solar cells, which are the core part of the solar power system and the most important part of the solar power system. The main ingredient is "silicon".
　　 With the increasing demand for clean energy from mankind, solar power generation has attracted more and more attention. At present, the mainstream solar power generation equipment on the market mainly uses solar panels as an intermediate medium to convert solar energy into electrical energy, thereby promoting the work of the entire load. Solar panels are mainly composed of glass, solar panels, backplanes, EVA, junction boxes, aluminum frames, etc. The operational reliability and price cost of each component will directly affect the service life and sales price of solar panels, which in turn will affect The entire solar power system.

Solar panels are currently the mainstream solar power generation equipment, which has the advantages of long development history, low manufacturing cost, and high photoelectric conversion efficiency. Solar panels are mainly composed of cells, glass, backsheets, EVA (Ethylenevinyl acetate), aluminum frames, junction boxes, etc. How to choose components with low cost and high operational reliability has become the main research topic of various battery manufacturers . When solar panels are used outdoors, they are affected by geographic and climatic conditions. For this reason, system designers need to consider the feasibility of the design scheme and the maximization of energy output from many aspects.
　　Solar panel structure and production process
　　The solar panel is mainly composed of aluminum frame, glass, high permeability EVA, solar cell, high cut-off EVA, backplane, junction box and other parts.
　　The main components of solar panels
Cell
According to the different preparation processes of the solar cells, it is mainly divided into single crystal solar cells and polycrystalline solar cells. Among them, the single crystal mainly adopts the pulling method to grow silicon rods, and the polycrystalline mainly adopts the ingot method to grow silicon ingots. Due to the different growth methods, The internal lattice structure, low light response and conversion efficiency of the two cells are different.
