Abstract: (622 Views)
In this paper, the pouring time of anti-solvent in one-step method to perovskite deposition and its effects on the performance of perovskite solar cells was investigated. For this purpose photoluminescence (PL), current-voltage and X-ray diffraction (XRD) analyzes were used. It was observed that the shorter time interval between the start of the deposition and the pouring of anti-solvent lead to the lower peak intensity of the PL spectrum of the perovskite layer, the higher peak intensity of the perovskite in XRD and so the efficiency of the built solar cell will be higher. According to the results, the optimal time for pouring the anti-solvent was 20 seconds remained before the coating was completed compared to other times, and the efficiency of the constructed solar cell at this time was 5.7%.
