Optical and electrical analysis for high power conversion efficiency hybrid perovskite solar cells

Perovskite materials have been successfully investigated in solar cells applications in order to deliver high power conversion efficiency (PCE). In this paper, we assess the performance of cesium-formamidinium-based mixed-halide perovskite with varied bandgap for perovskite solar cell (PSC) applications, and we derive their sensitivity under high-temperature conditions. A proposed combined optoelectronic model is used to optimize PSC and achieve the highest PCEs. Our Simulated results highlight that appropriate bandgap engineering of 1.62 Ev, optimal interface materials and thickness of the perovskite absorber lead to significantly higher PCE over 20% for PSC. Of critical importance, the temperature sensitivity of PSC is decreased as compared to the crystalline-silicon solar cell device under high-temperature conditions. Thus, our work shows that PSC under optimal characteristics could be the possible new guidance for manufacturing solar cells of higher PCEs and low cost.
