Embodiment 1
[0043] refer to figure 1 A method for preparing the biodegradable flexible perovskite solar cell proposed by the present invention comprises the following steps:
[0044] S1. At 80°C, disperse 12mmol of zinc acetate dihydrate powder in 200mL of continuously stirring ethanol to obtain solution A; dissolve 10mmol of KOH in 90mL of ethanol to obtain solution B; dissolve solution B within 10min Add dropwise to solution A at 80°C, stir at 80°C for 4 hours, stop heating, cool to room temperature, filter, and let the filtrate stand for 24 hours to obtain a mixed solution; take 0.3mL of the above mixed solution and spin-coat it on a glass substrate , heated it at 80°C for 50min to form a ZnO sacrificial layer on the surface of the glass substrate to obtain a coated substrate; use O 2 Plasma pretreat the ZnO sacrificial layer on the coated substrate for 5 minutes, take another glass substrate, place it at a certain angle with the coated substrate, heat the coated substrate to 70°C, ta...
