Abstract

The invention relates to a perovskite solar cell containing a protective layer. The perovskite solar cell comprises FTO conductive glass, an electron transport layer, a perovskite layer, a hole transport layer, a protective layer and a top electrode, wherein the protective layer comprises a water vapor barrier material and a co-doped [pi] conjugated conductive high polymer material; the water vapor barrier material is any one or a mixture of two of organic silicon resin, organic titanium resin and organic zirconium resin; the co-doped [pi] conjugated conductive high polymer material is one ora mixture of two of sulfo-doped polypyrrole, polythiophene and polyaniline conductive high polymers; and a conductive accelerant is added into the protective layer. The water vapor barrier material can protect the perovskite layer from water vapor and can weaken corrosion of the perovskite layer to the top electrode, and the co-doped [pi] conjugated conductive high polymer material can improve theconductivity of the water vapor barrier material. The protective layer can effectively improve the stability of the perovskite solar cell.

Description

technical field [0001] The invention relates to a perovskite solar cell containing a protective layer and a preparation method thereof, belonging to the technical field of solar cells. Background technique [0002] In recent years, with the deteriorating global climate and the continuous consumption of non-renewable energy, it is imminent for people to utilize clean and renewable energy. Solar energy has attracted much attention due to its advantages of cleanliness, large reserves, and wide distribution. In the utilization of solar energy, the conversion of light energy into electrical energy is an important utilization method. The device that converts light energy into electrical energy is a solar cell. At present, there are silicon solar cells and CIGS thin-film solar cells that are commercialized. However, due to the high cost of these two cells and the relatively large pollution in the production process, scientists have been looking for a Perovskite cells have emerged...
