Abstract

Perovskites are hybrid materials containing templating organic linkers and inorganic halides with efficiencies that have superseded the efficiency of silicon-based photovoltaic devices (PVs) in a very short period of 10 years. Nevertheless, low ambient stability due to traps and ion migration caused hysteresis to remain the bottlenecks on the way to achieving higher operational stability with bulk perovskite-based PVs. In this context, herein we highlight the prospects of in situ cross-linking of linkers within the perovskite lattice either mediated by thermal means or attained photochemically that can maneuver the ambient as well as operational stability for enhanced power conversion efficiency for PV applications or could improve the conductivity of this hybrid semiconductor. Additionally, some important studies of additive engineering via in situ cross-linking that can affect the structure of perovskite in addition to defect passivation to endow ambient environment stability are highlighted herein.

原位交联块状过氧化物以实现高效稳定的光伏技术。

过氧化物是一种含有模板有机连接体和无机卤化物的混合材料，其效率在很短的 10 年内就超过了硅基光伏设备（PV）。尽管如此，由于陷阱和离子迁移导致的环境稳定性低、滞后等问题，仍然是阻碍块状透辉石光伏器件实现更高的运行稳定性的瓶颈。在这种情况下，我们在本文中强调了在透辉石晶格内原位交联连接体的前景，这种交联连接体可以通过热手段或光化学方法实现，从而提高环境稳定性和运行稳定性，以提高光伏应用的功率转换效率，或改善这种混合半导体的导电性。此外，本文还重点介绍了通过原位交联对添加剂工程进行的一些重要研究，除了缺陷钝化之外，这些添加剂工程还能影响包晶的结构，从而赋予其环境稳定性。

期刊介绍： The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
