At present, crystalline silicon solar cells are widely used, occupying the main market of solar cells. However, crystals are currently widely used in crystalline silicon solar cells, occupying the main market for solar cells. However, crystalline silicon solar cells have inherent weaknesses: the forbidden band width of silicon materials is Eg=1.12eV, and the
solar photovoltaic conversion efficiency is relatively low; the silicon material is an indirect band material, and the light absorption coefficient of silicon is far in the visible range. Far less than other solar photovoltaic materials, such as the same absorption of 95% of sunlight, GaAs solar cells only need 5 to 10 microns thickness, while silicon solar cells require more than 150 microns thickness; therefore, when preparing crystalline silicon solar cells The thickness of the silicon wafer is 150-200 microns or more to effectively absorb solar energy; the crystalline silicon material needs to be purified several times, and the relative cost is relatively high; the size of the silicon solar cell is relatively small, and if the photovoltaic system is composed, it is necessary to use dozens of the same The silicon solar cells are connected together, resulting in higher system cost. Therefore, thin-film solar cells have attracted people's interest and have a certain degree of industrial application.
As a leading enterprise in the galvanized & pre-painted industry in china. Shandong Xinghan Materail Corporation with an annual output of 1 million tons of picking coils. 1 million tons of cold roll. 800,000 tons of hot-dipped galvanized and galvalume steel sheets. 450,000 tons of thicker galvanized steeel sheets.300,000 tons of pre-painted steel sheets. occupies a stable leading position in the industry.
The company has 4 set of cutting and corrugated machines.It is a further produce on basis of GI/GL or Pre-painted products. Coruugated sheets range 0.12mm-0.45mm, width range 650-1100mm.
