As shown in fig. 3 (a represents the conventional solar cell, and B represents the silver electrode perovskite solar cell), the conventional solar cell has the minimum value of the ID at-0.5V, while the curve of the silver electrode perovskite solar cell is in a right-shift trend, the voltage value corresponding to the minimum value of the ID is also right-shifted, and it can be clearly seen that the ID of the silver electrode perovskite solar cell is reduced compared with that of the conventional solar cell. Compared with the traditional solar cell, the silver electrode perovskite solar cell has the advantages that the surface defect states are reduced, and the performance of the cell is improved.
It is worth to say that the solar cell prepared by the method is structurally characterized by comprising an FTO substrate, a SnO2 thin film layer, a perovskite layer, a Spiro-OMeTAD thin film layer and Ag, silver serving as a top electrode can bring good conductivity, and organic matter Spiro-OMeTAD serving as a hole transport layer material can bring high filling factors, so that the perovskite solar cell with the silver electrode is more stable in performance.
