Embodiment 1
[0026] (1) Use toluene, acetone, ethanol, and deionized water in sequence to ultrasonically clean the ITO glass substrate for 5 minutes, and then dry the substrate with a nitrogen gun for later use;
[0027] (2) Deposit the ZnO electron transport layer 2 on the ITO conductive film of the cleaned ITO glass substrate by magnetron sputtering. The target used for sputtering is a ZnO target with a diameter of 46 mm and a copper back target of 50 mm, Ar and O 2 The gas flow rate is 40sccm, the reaction chamber pressure is set to 20mTorr, the sputtering power of the RF source is set to 70W, the target speed is 25 rpm, and the final deposition thickness is 50nm;
[0028] (3) Depositing PbBr on the ZnO electron transport layer by thermal evaporation 2 layer, and then soak the obtained device into a saturated ethanol solution of CsBr for 15 minutes, and anneal at 85°C for 25 minutes after the reaction is complete, and prepare the inorganic perovskite CsPbBr 3 Thin film light emitting ...
