Abstract

The invention discloses a perovskite solar battery and a preparation method thereof. The perovskite solar battery sequentially comprises a transparent electrode, a mesoporous p-i-n structure frame and a counter electrode from bottom to top; the mesoporous p-i-n structure frame is composed of an n-type semiconductor layer, an insulating layer, and a p-type semiconductor layer in a sequentially stacked mode, and the n-type semiconductor layer, the insulating layer and the p-type semiconductor layer all comprise mesopores filled with a perovskite material. The preparation method sequentially includes preparing the mesoporous p-i-n structure frame on a transparent conductive substrate through a spin-coating method or a screen printing method, filling the perovskite material and preparing the counter electrode layer. The perovskite solar battery can simplify the preparation process and reduce production costs by using the mesoporous p-i-n structure frame, effectively ensures the energy conversion efficiency of solar batteries and has a good prospect for industrial application.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and more specifically relates to a perovskite solar cell and a preparation method thereof. Background technique [0002] Energy is the driving force for the development and progress of human society, and an important material basis for the development of the national economy and the improvement of people's living standards. With the massive consumption of traditional fossil energy, environmental pollution is becoming more and more serious, and the global energy crisis is becoming increasingly prominent. Solar cells directly convert solar energy into electrical energy, which is one of the important methods to solve the global energy crisis and reduce environmental pollution. At present, silicon-based solar cell technology is the most mature and widely used, but the raw material purity and crystallinity of silicon-based solar cells are high, the process is complicated, and the preparation cost...
