Colorful Solar Panel

                polycrystalline silicon solar panel: Basically, polycrystalline silicon solar panel, as the name suggests, comes from a plurality of crystalline silica substrates, is currently the most common type of panels. The efficiency of the solar panel is slightly lower than that of the monocrystalline silicon, but when combined into a solar array, the number of watts in a single solar panel is smaller than that of the former. At present, more than the domestic trial is polycrystalline solar panels, the battery board also needs to be encapsulated in epoxy resin or sandwiched in the glass substrate for protection.Colorful Solar Panel

                Solar cell classification: commonly used in the community of silicon solar cells are divided into monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells. Monocrystalline silicon solar cell conversion efficiency is the highest, technology is also the most mature. In the laboratory the highest conversion efficiency is 24.7%, and the efficiency of scale production is 15%. In large-scale applications and industrial production is still dominant, but because of the high cost of monocrystalline silicon, significantly reduce its cost is very difficult, in order to save silicon materials, the development of polycrystalline silicon thin film and amorphous film as a silicon solar cell replacement products. polycrystalline silicon thin film solar cells compared with monocrystalline silicon, the cost is low, but the efficiency is higher than amorphous si thin film battery, its laboratory maximum conversion efficiency is 18%, industrial scale production conversion efficiency is 10%. Therefore, polycrystalline silicon thin film batteries will soon dominate the solar power market.Colorful Solar Panel

               The principle of solar cells: solar illumination in the semiconductor n Junction, the formation of a new hole-electron pair, under the action of N Junction electric field, the hole from the N region to P, the electron from P region to N, the circuit after the formation of electricity. This is the working principle of photoelectric effect solar cells.Colorful Solar Panel
