Abstract

Metal-organic frameworks (MOFs) with tailorable structures and building blocks have demonstrated their advantages in improving the long-term stability of perovskite solar cells (PSCs). However, the inferior conductivity of MOFs and their lack of strong chemical interaction with perovskites cause undesirable interfacial charge carrier recombination and then deteriorate the photovoltaic (PV) performance of PSCs. This perspective offers an insightful overview of the versatile functionalities and key merits of MOFs for stabilizing PSCs under various external stimuli in terms of MOF interlayers and MOF-perovskite heterostructures. To tackle the charge transport problem of MOFs, promising strategies are outlined to improve the intrinsic conductivity and chemical coordination of MOFs, with the aim of achieving long-term stable PSCs without compromising their PV performance. The current challenging issues and potential solutions are also discussed to provide a roadmap for MOF-tailored PSCs towards practical applications.

金属有机框架定制钙钛矿太阳能电池

具有可定制结构和构建块的金属有机框架(MOFs)在提高钙钛矿太阳能电池(PSCs)的长期稳定性方面具有优势。然而，由于mof的电导率较差，且与钙钛矿缺乏强的化学相互作用，导致PSCs的界面载流子重组，从而降低了其光伏(PV)性能。从MOF中间层和MOF-钙钛矿异质结构的角度，对MOF在各种外部刺激下稳定psc的多功能和关键优点进行了深刻的概述。为了解决mof的电荷输运问题，概述了改善mof的内在电导率和化学配位的有希望的策略，目的是在不影响其PV性能的情况下实现长期稳定的PSCs。本文还讨论了当前具有挑战性的问题和潜在的解决方案，为mof定制PSCs走向实际应用提供了路线图。

期刊介绍： Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover: • Novel micro and nanostructures • Nanomaterials (nanowires, nanodots, 2D materials ) and devices • Synthetic heterostructures • Plasmonics • Micro and nano-defects in materials (semiconductor, metal and insulators) • Surfaces and interfaces of thin films In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board. Formerly known as Superlattices and Microstructures, with a 2021 IF of 3.22 and 2021 CiteScore of 5.4
