Problems solved by technology

Therefore, in order to improve the light transmittance, people continue to improve the structure of the transparent conductive film that affects the light transmittance, conductivity and scattering of conductive glass, increase the number of layers of the metal oxide conductive layer, and add a layer of metal oxide conductive layer It is changed to multi-layer, but the multi-layer metal oxide conductive layers are still physically superimposed, and the transparent conductive film layer structure is single and the stability is poor. These improved transparent conductive film layer structures have not changed the performance of conductive glass in essence. , the light transmittance, conductivity and scattering degree of conductive glass have not been greatly improved

As a result, very huge solar energy cannot be fully utilized and converted, which reduces the conversion efficiency of solar energy and increases the cost of use
