AbstractOver the past number of years, the power conversion efficiency of perovskite solar cells has remained at 25.5%, reflecting a respectable result for the general incorporation of organometallic trihalide perovskite solar cells. However, perovskite solar cells still suffer from long-term stability issues. Perovskite decomposes upon exposure to moisture, thermal, and UV-A light. Studies related to this context have remained ongoing. Recently, research was mainly conducted on the stability of perovskite against non-radiative recombination. This study improved a critical instability in perovskite solar cells arising from non-radiative recombination and UV-A light using a passivation layer. The passivation layer comprised a polyaniline (PANI) polymer as an interfacial modifier inserted between the active layer and the electron transport layer. Accordingly, the UV-A light did not reach the active layer and confined the Pb2+ ions at PANI passivation layer. This study optimized the perovskite solar cells by controlling the concentration, thickness and drying conditions of the PANI passivation layer. As a result, the efficiency of the perovskite solar cell was achieved 15.1% and showed over 84% maintain in efficiency in the ambient air for one month using the 65 nm PANI passivation layer.

Vacuum-assisted thermal annealing not only could improve film morphology and crystallinity, but also could accelerate the sublimation of undesired MACl. With the help of this process, we obtain a highly efficient low-bandgap CH3NH3Sn0.5Pb0.5IxCl3−x perovskite solar cell with a power conversion efficiency of 12.3%.

Halide Perovskite

Perovskite solar cell is categorized as a third-generation solar cell which is used for its high-performance and low-cost production. However, device stability is a major problem in the development of perovskite solar cells. Mixed halide perovskite is one of the subjects that have been proposed to improve perovskite solar cell stability. Research about solar cells using mixed halide perovskite is widely reported. However, complex configurations and fabrication using sophisticated equipment were usually used in those reported studies. In this work, the fabrication of solar cells using mixed halide perovskite CH3NH3PbI3- x Cl x and CH3NH3PbI3- x SCN x was conducted using a simple and low-cost structure. Solution-processed deposition fabrication method using spin coating was used to fabricate the devices. Optimization of the spin coating rate for each layer in the perovskite solar cells was performed to ensure that the devices exhibited decent performance. Stability measurement and analysis of the perovskite solar cells were conducted. Summarily, solar cells with mixed halide perovskite CH3NH3PbI3- x Cl x exhibit the highest performance with an efficiency of 2.92%. On the other hand, solar cell with mixed halide perovskite CH3NH3PbI3- x SCN x has the best stability which only drops its efficiency by 39% from its initial value after 13 days.
