Abstract

The invention relates to an internal series perovskite battery assembly. The perovskite battery assembly sequentially comprises a substrate, a conductive layer, a front electrical transmission layer,a perovskite layer, a rear electrical transmission layer and a back electrode layer from bottom to top; n-1 cutting line grooves P1 are formed in the front electric transmission layer; the cutting line grooves P1 cut off the front electrical transmission layer and the conductive layer at the same time; n-1 cutting line grooves P2.5 are formed in the rear electric transmission layer; each cutting line groove P2.5 is positioned on one side of the corresponding cutting line groove P1; the rear electric transmission layer and the perovskite layer are cut off at the same time by the cutting line grooves P2.5; n-1 cutting line grooves P3 are formed in the back electrode layer; the cutting line grooves P3 cut off the back electrode layer, the rear electric transmission layer and the perovskite layer at the same time; and the perovskite battery assembly is divided into n internal series perovskite battery sub-batteries under the combined action of the n-1 cutting line grooves P1, the cutting line groove P2.5 and the cutting line groove P3. The invention also provides a preparation method of the assembly. According to the internal series perovskite battery assembly of the invention, the influence of metal electrodes on the perovskite layer can be effectively inhibited.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and in particular relates to an inner series perovskite cell assembly and a preparation method thereof. Background technique [0002] Existing solutions for preparing perovskite solar cells by laser are only suitable for preparing small-area solar cells for scientific research and cannot be mass-produced. The perovskite batteries prepared in the laboratory are all small in size and cannot be commercialized, while the same method of preparing large-area batteries will cause various problems and reduce efficiency. How to prepare high-efficiency large-area perovskite battery components has always been a problem. Another major bottleneck limiting the commercial development of perovskite solar cells is the stability of the cells. Experiments have shown that the perovskite layer in traditional perovskite batteries is easy to react with metal electrodes and deteriorate, which greatly reduces bat...
