ITO used in solar cells in the plasma is not stable enough, so the current ITO coating has been non-photovoltaic cell mainstream electrode glass. SnO2 coating also referred to as FTO, is mainly used for Wood Plastic Fence, Wood Plastic Composite Supplier - Shanghai Seven Trust the production of low-E glass building. Its conductivity is slightly worse than ITO, but with relatively low cost, easy laser etching, optical performance and other advantages. Through the upgrading of the production technology eco cladding plank for sale of ordinary Low-E to improve the manufacture of the conductivity than the ordinary Low-E good, and with the haze of the product. The use of this technology to produce TCO glass has become a thin film photovoltaic cell mainstream products.
The research progress of zinc oxide-based thin films is rapid and the properties of the materials can be compared with those of ITO. The structure paintable composite tongue and groove deck board Italy is hexagonal wurtzite type. The research of aluminum-doped zinc oxide thin films is more extensive, and its outstanding advantage is that the raw materials are easy to obtain, the manufacturing cost is low, the non-toxic, easy to realize doping, and the stability in the plasma is good.
Photovoltaic cells for TCO coated glass performance requirements Spectral transmittance In order to be able to make full use of sunlight, TCO coated glass must maintain a relatively high transmittance. At present, the largest yield of thin-film batteries is double-junction amorphous silicon cells, and has begun to perspex fence panels uk amorphous / microcrystalline composite battery conversion. Therefore, the amorphous / microcrystal composite stack can absorb the use of more sunlight, improve the conversion efficiency, will soon become the mainstream of thin film batteries.
