A Review of Bifacial Perovskite Solar Cells

Bifacial perovskite solar cells (B-PSCs) have emerged as a promising solution to enhance photovoltaic efficiency by harvesting light from both front and rear surfaces. While perovskite materials offer high power conversion efficiency and low-cost fabrication, traditional single-sided architectures limit their energy-harvesting potential. The purpose of this research is to systematically analyze recent progress in materials design, device architecture, and optical management strategies for B-PSCs. Key results indicate that optimized electrodes and interlayers significantly improve rear-side transparency, responsivity and overall energy yield. B-PSCs represent a viable pathway toward next-generation, high-efficiency photovoltaics, though further work is needed to address stability, large-scale production, and long-term operational performance.
