Perovskite solar cells (PSCs) exhibit a series of distinctive features in their optoelectronic response which have a crucial influence on the performance, particularly for long‐time response. Here, a survey of recent advances both in device simulation and optoelectronic and photovoltaic responses is provided, with the aim of comprehensively covering recent advances. Device simulations are included with clarifying discussions about the implications of classical drift–diffusion modeling and the inclusion of ionic charged layers near the outer carrier selective contacts. The outcomes of several transient techniques are summarized, along with the discussion of impedance and capacitive responses upon variation of bias voltage and irradiance level. In relation to the capacitive response, a discussion on the J–V curve hysteresis is also included. Although alternative models and explanations are included in the discussion, the review relies upon a key mechanism able to yield most of the rich experimental responses. Particularly for state‐of‐the‐art solar cells exhibiting efficiencies around or exceeding 20%, outer interfaces play a determining role on the PSC's performance. The ionic and electronic kinetics in the vicinity of the interfaces, coupled to surface recombination and carrier extraction mechanisms, should be carefully explored to progress further in performance enhancement.

钙钛矿杂化太阳能电池的器件物理：理论与实验

钙钛矿太阳能电池（PSC）在其光电响应中表现出一系列独特的特征，这些特征对性能（尤其是长期响应）具有至关重要的影响。在此，提供了对器件仿真以及光电和光伏响应方面最新进展的调查，目的是全面涵盖最新进展。器件仿真包括有关经典漂移扩散模型的含义以及在外部载流子选择性接触附近包含离子带电层的含义的澄清讨论。总结了几种瞬态技术的成果，并讨论了偏置电压和辐照度变化时的阻抗和电容响应。关于电容响应，关于J–V的讨论曲线磁滞也包括在内。尽管讨论中包括了替代模型和解释，但该综述依赖于一种能够产生大多数丰富实验响应的关键机制。特别是对于显示出约20％或超过20％的效率的最先进的太阳能电池，外部界面对PSC的性能起着决定性的作用。应仔细研究界面附近的离子动力学和电子动力学，以及表面重组和载流子提取机理，以进一步提高性能。
