“…Similar device configuration was employed by Chiang et al They synthesized indium‐doped zinc oxide (IZO) nanoparticles by solution process with the assistance of microwave as ETL and NiO x as HTL . In general, ZnO‐based PSCs suffered from low fill factor, because of the carrier transport loss within the ZnO nanoparticles.…”

IntroductionIn recent decades, the world has come to a consensus that new green energy sources are vital for sustainable development. Solar energy has been regarded as an alternative source of energy supply. Photovoltaic (PV) technology has progressed for decades with massive efforts devoted. Alternative technologies for photon to electron power conversion include, for instance, This review presents various hole transport layers (HTLs) employed in perovskite solar cells (PSCs) in pursuing high power conversion efficiency (PCE) and functional stability. The PSCs have achieved high PCE (over 23%, certified by NREL) and more efforts have been devoted into research for stability enhancement. Inorganic HTLs become a popular choice as selective contact materials because of their intrinsic chemical stability and low cost. HTLs and electron transport layers (ETLs) are critical components of PSCs due to the requirement to create charge collection selectivity. Herein the authors provide an overview on inorganic HTLs synthesis, properties, and their application in various PSCs for both mesoporous and planar architectures. InorganicHTLs with appropriate properties, such as proper energy level and high carrier mobility, can not only assist with charge transport, but also improve the stability of PSCs under ambient conditions. The importance of interfacial chemistry and interfacial charge transport is further addressed to understand the underlying mechanism of related degradation and carrier dynamic. It is expected that the success of the inorganic HTL in PSCs can stimulate further research and bring real impact for future photovoltaic technologies.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/admi.201800882. super-mesostructure Al 2 O 3 scaffold, achieving a PCE above 9% [6] and 10%, [7] respectively.

Nickel oxide (NiO) materials with excellent stability and favorable energy bands are desirable candidates for hole‐selective contact (HSC) of inverted perovskite solar cell (PSC). However, studies that focus on addressing interfacial issues, which are induced by the poor NiO/perovskite contact or other defects, are scarce. In this study, a facile one‐step hydrothermal strategy is demonstrated for the development of a 3 D NiO nanowall (NW) film as a promising HSC. The new NiO NWs HSC exhibits a robust and homogenous mesoporous network structure, which improved the NiO/perovskite interface contact, passivated the interfacial defect and improved the quality of the perovskite film. The optimized interface features enabled a power conversion efficiency (PCE) approaching 18 %. A diethanolamine (DEA) interlayer was introduced to further passivate the intrinsic defect of the NiO surface, resulting in better charge transfer with suppressed recombination loss. As a result, the champion PCE of the NiO NWs/DEA‐based device was increased to 19.16 % with a high open‐circuit voltage (≈1.11 V) and fill factor (>80 %), which is prominent in methylammonium lead iodide‐based inverted PSCs. Furthermore, the device exhibited better stability and lower hysteresis behavior than a conventional solution‐based NiO nanocrystal device.

With the rapid developments in lead halide perovskite solar cell technology, record-high power conversion efficiencies have been achieved, and significant research efforts have been directed toward stability, which is still a major challenge facing the commercialization of perovskite solar cell technology. In this review article, we review the research progress that has been made on the stability of perovskite solar cells. We start with an analysis of recently reported operational stability profiles of perovskite solar cells. On the basis of the analysis, we determine the solar cell lifetime (i.e., T 80 values) and the total amount of energy generated during the lifespan of a perovskite solar cell, from which several trends are inferred. In the subsequent sections, we further examine the instability issues associated with various constituents in a perovskite solar cell and the new methods/strategies that have been developed to solve these issues.
