Device Optimization of PIN Structured Perovskite Solar Cells: Impact of Design Variants

Abstract

[EN] Numerical analysis is a tool that is helping engineers over the past decades in design optimization and low-cost fabrication of solar cell devices. The need of modeling tools is used to deeply analyze a device in a soft environment where the time and cost both can be saved before putting a device into fabrication. In this study, lead iodide-based perovskite solar cells were modeled having several feasible planar pin structures for known electron and hole transport layers. The primarily taken pin device structure for analysis was PEDOT:PSS/MAPbI(3)(I)/PCBM. A total of seventy-two different structures were analyzed. From our results, thirty-seven devices have achieved a maximum efficiency of 21%. The best device structure has achieved a 23.29% PCE. Our proposed results can provide imperative guidelines to researchers for the design of efficient pin structure perovskite solar cells.
