Abstract

The invention discloses a perovskite solar cell based on a full-sol-gel process and a preparation method thereof. The perovskite solar cell based on the full-sol-gel process includes a conductive glass substrate (14), a metal oxide layer (13), a perovskite film layer (12), a hole transportation layer (11), and a back electrode contact layer (10) sequentially from top to bottom. A conductive thin film is arranged on the conductive glass substrate (14). The back electrode contact layer (10) is an ITO (indium tin oxide) layer and substitutes traditional Au and Ag and the like and at the same time, BaTiO3, ZnO, and SnO2 and the like are used as the metal oxide layer so that it is realized that in a preparation process, the sol-gel process is used so that the manufacturing cost is reduced and at the same time, the preparation process is simplified and large-area manufacturing is facilitated.

Description

Technical field [0001] The invention relates to the technical field of solar photovoltaic utilization, and more specifically to a perovskite solar cell based on a full sol-gel process and a preparation method thereof. Background technique [0002] The phenomenon of photoelectric conversion was first observed by French scientist Henri Becqμerel in 1839. In 1954, the first usable silicon-based solar cell came out. It was a solar cell with a pn junction. This pn junction solar cell uses sunlight to generate working current to provide electricity to the outside world. Silicon-based solar cells have gradually entered the market. However, from a global perspective, due to the high manufacturing cost of silicon-based cells, the installation of photovoltaic cells The capacity is very limited. In addition, silicon-based solar cells are not conducive to manufacturing with flexible materials, and there are obstacles to large-scale production. In 1991, Swiss scientist Glanzell Dye Sensiti...
