Abstract
Abstract Herein, we develop an inverted p−i−n structured ferroelectric solar cell based on polycrystalline bismuth ferrite (BiFeO3) thin films, achieving a power conversion efficiency of 3.67%. Unlike conventional in-plane configurations, this architecture offers enhanced design flexibility and facilitates the integration of low-temperature-processed n-type semiconductors by placing the p-type layer at the bottom, thereby improving process compatibility. Inspired by inverted perovskite solar cells, this design significantly boosts carrier collection efficiency and fabrication feasibility. Our results underscore that rational device engineering is critical to advancing ferroelectric photovoltaics, providing a promising pathway toward solution-processable, non-silicon solar energy conversion.
