Abstract
A hybrid solar cell with zinc oxysulfide serving as an electron transfer layer is composed of a transparent conducting glass substrate, the zinc oxysulfide electron transfer layer, an inorganic hybrid perovskite material, a 2,2',7,7'-tetrakis[N,N-di(4-nethoxyphenyl)amino]-9,9'-spirobifluorene hole transport layer and an Au metal back electrode layer, wherein the zinc oxysulfide electron transfer layer, the inorganic hybrid perovskite material, the 2,2',7,7'-tetrakis[N,N-di(4-nethoxyphenyl)amino]-9,9'-spirobifluorene hole transport layer and the Au metal back electrode layer are sequentially combined to form a laminated structure, the inorganic hybrid perovskite material is CH3NH3PbX3, and X is Cl or Br or I. The hybrid solar cell and a preparation method have the advantages that the hybrid solar cell has the large specific surface area and the good electron transfer capacity when the zinc oxysulfide serves as the electron transfer layer, electron-hole combination is effectively restrained, the photoelectric conversion efficiency is high, and the preparation method is simple in process, low in reaction temperature, high in efficiency, abundant in raw materials, low in cost, green, free of pollution, and suitable of industrial large-scale production.
Description
technical field [0001] The invention relates to the field of organic photoelectric-solar cells, in particular to a hybrid solar cell with zinc oxysulfide as an electron transport layer and its preparation. Background technique [0002] With the increasing depletion of global oil resources, solar cells have become a frontier subject of extensive research as a feasible method to solve the world's energy crisis. The research and development of solar cells has always been carried out around the following two key issues: 1) Improving photoelectric conversion efficiency and life; 2) Using new materials to reduce costs. So far, the high temperature and high vacuum required in the preparation process of inorganic photovoltaic cells make the production cost of inorganic photovoltaic cells very high, which greatly limits its application. Organic polymer bulk heterojunction photovoltaic cells are low in cost, non-toxic, easy to prepare, easy to realize flexible devices, and can conve...
