Materials and Methods for Interface Engineering toward Stable and Efficient Perovskite Solar Cells
Abstract
Because interfacial nonradiative recombination (NRR) has a significant influence on device performance, the minimization of interfacial NRR losses through interface engineering especially for perovskite-related interfaces is key to achieving efficient, stable, and hysteresis-free perovskite solar cells (PSCs). In light of important contributions of interface engineering to rapid development of PSCs, a systematic investigation and analysis on the latest research advancements on interface engineering is urgently needed. This Review aims at providing innovative insights into further improvement in power conversion efficiency (PCE) toward the Shockley–Queisser limit efficiency and stability fulfilling commercially available standard protocols as well as reduction of hysteresis. In this Review, the roles and importance of interfaces in PSCs are first highlighted from the viewpoint of device structure, working principles, and interfacial carrier dynamics. The main origins (i.e., interface defects, imperfect energy level alignment (ELA), and interfacial reactions) of interfacial NRR are then discussed in detail along with characterization techniques. Subsequently, the effects of interfacial NRR on PCE, stability, and hysteresis are investigated. Strategies for mitigating interfacial NRR are provided in terms of defect passivation, ELA modulation, and suppression of interfacial reaction, where the critical roles of functional groups of interface modifiers are emphasized. Finally, we provide an outlook for efficient, hysteresis-free, and long-term operationally stable PSCs achievable via interface engineering.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
