“…Compared with PC 61 BM‐based PSCs, the efficiency is increased by about 15% and the hysteresis is negligible. Furthermore, yttrium (Y)‐doped SnO 2 nanosheets, [ 191 ] graphitic carbon nitride (g‐C 3 N 4 )‐doped SnO 2 , [ 192 ] poly[9,9‐bis(6′‐( N , N ‐diethylamino)propyl)‐fluorene‐alt‐9,9‐bis(3‐ethyl (oxetane‐3‐ethyloxy)‐hexyl) fluorene] (PFNOX)‐doped PC 61 BM, [ 193 ] indium (In)‐doped ZnO nanofibers, [ 194 ] and N‐doped ZnO nanosheets [ 195 ] also have important reference significance in reduce hysteresis and improve performance of PSCs. In addition to doping with other elements, the application of new preparation techniques can also improve performance and suppress the hysteresis.…”

The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has exceeded 25%, showing great potential in the photovoltaic field. However, PSCs often show anomalous current density–voltage (J–V) hysteresis behavior in the forward and reverse scanning directions, which makes it impossible to accurately evaluate the performance of PSCs. Therefore, it is necessary to clearly understand the mechanism of hysteresis and suppress the hysteresis. Herein, the J–V hysteresis behavior in PSCs and strategies to suppress hysteresis is focused: first, the various factors that affect J–V hysteresis in PSCs are summarized. And the mechanism behind the various possible origins of hysteresis and the challenges encountered are explored. Then, the strategies to suppress or eliminate the hysteresis are summarized, including optimizing the perovskite light‐absorbing layer, improving the performance of the carrier transport layer and interface engineering. Finally, insights on the future development of the hysteresis are also provided.

“…Transition metal oxides (TMOs) are a possible substitute for traditional precious metal oxygen electrocatalyst, for they provide d‐orbital to bind oxygen species and are economical. But the spinel oxides still have limited activity and researchers are moving towards more efficient, low cost electrocatalyst for OER/HER & ORR 54,55 . Amongst TMOs, perovskite has an exceptional capability of accommodating multiple cations and allow partial substitution of cations at A‐site and B‐site.…”

The electrochemical water splitting by using renewable electricity is being considered as a sustainable, clean and considerable source of hydrogen fuel for future transportation and energy applications. The sluggish kinetics at anode and cathode, thus, require plenty of research work on the development of an efficient and stable electrocatalyst, which would provide the enhanced activity of water splitting reaction as well as stability for long-term operation. This review draws a detailed sketch of the progress in the pursuit of replacing noble metals with non-precious perovskite-based substitutes without compromising the key electrocatalyst characteristics. Herein, we critically analysed the latest research work and progress of perovskite oxides for anodic/oxygen reduction reaction/cathodic, including the mechanism behind perovskite oxide catalytic reactions, controlled composition as well as the role of various design strategies to achieve high catalytic performance. Moreover, the article also provides an insight to the associated density functional theory that can provide profound understanding of mechanism, involved behind these reactions and, the need for computational studies to exploit the active area of catalysts. It is believed that this article will assist researchers to explore key area of research in the current generation perovskites that show enhanced catalytic performance as well as to work on unforeseen challenges.
