摘要

有效利用红外光产生的热能一直是开发高效光伏（PV）器件的重点。理论上，热能可以通过热电（TE）效应转化为电能。然而，将PV和TE效应集成到光伏设备中用于太阳能到电力的转换，在很大程度上仍未被探索。在此，我们研究了钙钛矿太阳能电池（PSCs）在温度梯度（ΔT）下PV和TE的并发利用效应。在ΔT = 10 oC时，基于fapbi3的PSCs的功率转换效率（PCE）达到了创纪录的27.17%（平均26.87%），而对照组的PCE为25.65%（平均25.28%）。示例性PCE归因于太阳能的全光谱利用和内置温度梯度诱导的电荷载流子传输的定向调节，从而促进了它们的有效收集。我们的研究结果揭示了PV过程中的TE效应，并证明了PV和TE效应之间的协同合作对PSCs性能的提高。

Synergistic Cooperation between Photovoltaic and Thermoelectric Effects in Solar Cells

Efficient utilization of thermal energy generated from infrared light has long been a focal point in the development of high-efficiency photovoltaic (PV) devices. Theoretically, the thermal energy can be converted to electricity through the thermoelectric (TE) effect. However, integrating PV and TE effects in a PV device for solar-to-electricity conversion has remained largely unexplored. Herein, we investigated the concurrent utilization of PV and TE effects under a temperature gradient (ΔT) across perovskite solar cells (PSCs). A record power conversion efficiency (PCE) of 27.17% (26.87%, average) was achieved for FAPbI3-based PSCs at ΔT = 10 oC, compared to the control cases with PCE of 25.65% (25.28%, average). The exemplary PCE is attributed to full spectrum utilization of solar energy and directional regulation of charge carrier transport induced by built-in temperature gradients, which facilitates their efficient collection. Our findings reveal the TE effect in the PV process and demonstrate the synergistic cooperation between PV and TE effects for enhancing the performance of PSCs.
