Boosting the efficiency of an inverted structure halide perovskite solar cell: a numerical investigation
Inverted solar cells have attracted significant attention because they have low hysteresis and are resistant to environmental variables, such as oxygen and humidity, making them more stable and long-lasting. Herein, we investigate the performance optimisation of an inverted design based on MAPbI3-xClx with the structure ITO/PTAA/MAPbI3-xClx/PC60BM/BCP/Ag by utilising SCAPS-1D, a simulation tool. Accordingly, a substantial improvement in efficiency can be achieved by optimising several factors linked to each layer’s performance in a perovskite solar cell (PSC). Total defect density, work function, thickness, and electron affinity have a significant impact on the photovoltaic response. Specifically, the impact of optimisation of the charge transport layers and the perovskite layer on the device’s performance parameters was discussed, resulting in a milestone within a remarkable increase in PCE of 21.59%, whereas the original structure’s efficiency was 6.9%. Additionally, it has been shown that aluminium can substitute silver in the top electrode of a solar cell without affecting its efficiency, allowing the development of cost-effective solar cells. The present study provides an insight in the creation of a highly stable low-cost and higher-efficiency perovskite solar cell.
