Abstract

The invention discloses a carbon electrode material of a perovskite thin film solar cell and a preparation method of the carbon electrode material, and belongs to the field of preparation of photoelectric materials and nano films. The method is that the spray filming method is carried out to prepare a dense titanium dioxide thin film electronic transmission layer on a transparent conductive substrate; an organic metal halide of a perovskite structure is prepared on the dense titanium dioxide thin film to be used as a light absorbing layer; finally a hole transmission layer / carbon electrode layer is prepared on the perovskite thin film absorbing layer by the spray filming method, so as to obtain a carbon thin film which is the carbon electrode layer of the perovskite thin film solar cell. According to the method, the carbon material is used for replacing expensive precious metal to be used as the hole transmission electrode material, so that the cost can be reduced; the spray filming method which is simple, quick and capable of mass production is carried out, thus the cost is further saved, and the problems that the perovskite thin film solar cell is high in electrode cost, and the vacuum evaporation metal electrode preparation method is difficult to achieve mass production, can be solved; the method is applicable to low-temperature preparation of the electrode materials of large-area perovskite thin film solar cells.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a carbon electrode material for a perovskite solar cell and a preparation method thereof, and belongs to the field of photoelectric materials and nano film preparation. Background technique [0002] With the shortage of traditional fossil energy and increasingly serious environmental problems, high-efficiency, low-energy consumption, and pollution-free solar cells have attracted the attention of various countries. In 2009, Japanese scientist Miyasaka first used perovskite-based semiconductors for liquid-state sensitized solar cells. Among them, a photoelectric conversion efficiency of 3.8% has been achieved, but due to the corrosion of the electrolyte, the cell efficiency decays rapidly (J.Am.Chem.Soc.2009, 131, 6050.). With the deepening of research, the efficiency of perovskite solar cells has been further improved, and the highest efficiency certified by NREL has reached 1...
