Abstract

The invention discloses a preparation method for a perovskite solar cell with a tetramino zinc phthalocyanine organic hole transmission layer. The preparation method comprises the following steps of preparing tetranitro zinc phthalocyanine by a microwave method; reducing the tetranitro zinc phthalocyanine to tetramino zinc phthalocyanine; and spin-coating a derivative serving as the organic hole transmission layer onto a TiO2 film coated with perovskite to prepare the perovskite solar cell. By the preparation method, a phthalocyanine derivative dye-tetramino zinc phthalocyanine is synthesized and is taken as the organic hole transmission layer of the perovskite TiO2 solar cell, the reaction time is greatly reduced with the adoption of microwave synthesis energy, the reaction yield is improved, and the environmental pollution is reduced; and moreover, the green, environmental-friendly and high-efficiency perovskite solar cell based on the hole transmission layer made of the organic material is prepared.

Description

technical field [0001] The invention relates to a preparation method of a solar cell, in particular to a perovskite type solar cell, which is applied in the field of solar cell preparation technology. Background technique [0002] At present, the manufacturing cost of silicon-based solar cells, which dominates the market, has been greatly reduced, which will ensure that the large-scale use of photovoltaic cells in the future will become inevitable. According to recent forecasts, between now and 2030, photovoltaic power generation will account for one-third of the world's new power generation capacity. However, if it has very high photoelectric conversion efficiency or low manufacturing cost, it has the opportunity to replace traditional solar cells and become the next generation of new high-efficiency solar cells. [0003] Recently, the new generation of mixed organic-inorganic lead halide perovskites (CH 3 NH 3 wxya 3 , X=Cl, Br, I), has these two characteristics, showi...
