论文摘要
钙钛矿太阳能电池（PSC）是最有希望的下一代光伏技术之一，并且对有机无机卤化物钙钛矿（OIHPS）在光伏转换中可能极化的作用具有很大的兴趣。然而，OIHP的极性仍在争论。在这篇综述中，我们从理论和实验的观点中研究了有关OIHP的极性的最新文献，并认为它们可以是极性和非极性的，具体取决于组成，加工和环境。还讨论了OIHP极性对光伏转换的影响，并在回答这些问题方面的努力继续使我们提供新的见解。将来，将局部扫描探针与全球宏观测量中的原位集成在原位中，将为有趣的宏观现象提供宝贵的微观见解，而同步衍射和扫描透射电子显微镜在更稳定的样品上扫描透射电子显微镜可能最终可以解决辩论。
Perovskite solar cell (PSC) is one of the most promising next generation photovoltaic technologies, and there are considerable interests in the role of possible polarization of organic-inorganic halide perovskites (OIHPs) in photovoltaic conversion. The polarity of OIHPs, however, is still hotly debated. In this review, we examine recent literature on the polarity of OIHPs from both theoretical and experimental points of view, and argue that they can be both polar and nonpolar, depending on compositions, processing, and environments. Implications of OIHP polarity to photovoltaic conversion is also discussed, and effort in answering these questions continues to render us new insights. In the future, integrating local scanning probe with global macroscopic measurements in-situ will provide invaluable microscopic insight into the intriguing macroscopic phenomena, while synchrotron diffractions and scanning transmission electron microscopy on more stable samples may ultimately settle the debate.
