Abstract

The invention discloses an efficient stable perovskite solar cell and a preparation method thereof. The cell is characterized in that the cell structurally comprises a transparent conductive substrate, a window layer, a perovskite light absorption layer and an anti-ultraviolet hydrophobic layer from bottom to top in sequence. Compared with a traditional perovskite solar cell, the efficient stableperovskite solar cell has the advantages that one layer of anti-ultraviolet hydrophobic layer is added to the surface of the perovskite light absorption layer, on one hand, the anti-ultraviolet hydrophobic layer can have the dampproof and protective effects, and thus the perovskite light absorption layer is prevented from being hydrolyzed; on the other hand, the anti-ultraviolet hydrophobic layercan also absorb ultraviolet light, so that the perovskite light absorption layer is prevented from being photolyzed, and the ultraviolet light can be converted into visible light and can be used. Therefore, the efficient stable perovskite solar cell has remarkable advantages that the stability and photoelectric conversion efficiency of the efficient stable perovskite solar cell are improved.

Description

technical field [0001] The invention belongs to the field of new energy, and in particular relates to a high-efficiency and stable perovskite solar cell and a preparation method thereof. Background technique [0002] With the continuous progress and development of human society, the energy and environmental problems caused by industrial production are becoming more and more obvious. The limited reserves of fossil fuels (oil, coal, natural gas, etc.) and the global warming caused by their combustion make people We have to find and develop environmentally friendly and renewable new energy sources. The source of solar energy is abundant, inexhaustible, and environmentally friendly and non-polluting. It is one of the new energy sources that are expected to be applied on a large scale in the future. It has received extensive attention and research from the international community. Solar cells are the conversion of solar energy It is one of the important devices of electric energ...
