Embodiment 1
[0031] Example 1 Based on SNO 2 Electronic transport layer made of perovskite solar cells
[0032] Step 1: Cleaning and processing of FTO conductive substrate
[0033] The FTO conductive glass was sequentially washed with deionized water, ethanol, acetone and isopropanol, washed 30 min, and then the cleaning glass was dried in a drying tank and then treated with UV-ozone for 15 min.
[0034] Step 2: Preparation of Electronic Transport Layers
[0035] Sno 2 In combination with water, according to the volume ratio of 1: 3, the shock is mixed with a mixture of 0.22 μm aperture filtration, resulting in SNO 2 Solution. Sno 2 The solution was added dropwise on the conductive substrate, spin 30s at a rate of 3000 rpm, and then annealed on a thermometer at a temperature of 150 ° C for 30 min, and prepared an electron transport layer.
