Zinc oxide is a kind of sulfur hetero solar cell and the electron transport layer preparation

Zinc oxide is a kind of sulfur hetero solar cell electron transport layer, a transparent conductive glass substrate, a zinc oxide sulfur electron transport layer, an inorganic hybrid perovskite materials CH3NH3PbX3 (wherein X is Cl, Br or I), 2,2', 7,7'-tetrakis [N, N- bis (4-methoxyphenyl) amino] -9,9'-spirobifluorene hole transport layer and the metal back electrode layer composed of Au are sequentially stacked configuration structure. Advantages and positive effects of the present invention : in hybrid solar cells, using a zinc oxide sulfur as an electron transporting layer having a large specific surface area and good electron transport capability, electron - hole recombination It has been effectively suppressed, high photoelectric conversion efficiency; the preparation method is simple, low reaction temperature, high efficiency and abundant raw materials, low cost and no pollution green, suitable for industrial mass production.
