研究目的
To mitigate thermodynamic losses in perovskite solar cells by designing a novel prismatic perovskite solar cell with light trapping configuration.
研究成果
The newly designed prismatic perovskite solar cell (Prim PVSC) achieved a record open circuit voltage of 5.3 V and a power conversion efficiency of 21.3%, demonstrating a significant mitigation of thermodynamic losses. This architecture provides a new pathway to overcome the performance bottleneck of perovskite solar cells and could be applied in flexible modules for large-area applications.
研究不足
The study does not explicitly mention limitations, but potential areas for optimization could include the scalability of the device architecture and the long-term stability of the perovskite materials under operational conditions.
1：Experimental Design and Method Selection:
The study employed a novel prismatic perovskite solar cell design with light trapping configuration to modulate the pathway of light inside series cells.
2：Sample Selection and Data Sources:
Four horizontally aligned MAPbIxBr3?x subcells with varied bandgaps were used to separately capture incident high-to-low energy photons.
