Embodiment 1
[0028] The structure of a kind of perovskite solar cell of the present embodiment is as follows figure 1 As shown, it includes from top to bottom: PET cover film 7, gold electrode 6, AB glue 8, hole transport layer (HTL) 5, perovskite absorption layer 4, electron transport layer (ETL) 3, transparent conductive film ITO 2, transparent glass 1.
[0029] Wherein the perovskite light absorbing layer 4 is (FAPbI 3 ) x (MAPbBr 3 ) (1-x) , The ITO glass substrate is made of ITO glass etched with specific specifications, and the AB glue 8 uses Aibida high-temperature-resistant transparent AB glue that is not easy to react with perovskite materials.
[0030] see figure 1 , the invention provides a packaging method for a perovskite battery, comprising the steps of:
[0031] 1. On the ITO glass of 2.5cm * 2.5cm (wherein the transparent conductive film ITO 2 only exists in the middle 1.5cm * 2.5cm part) spin-coating prepares tin dioxide as electron transport layer 3.
