Clearly, in comparison with the former strategy, the latter is more cost-effective and technologically appealing. This underlines the importance of unveiling the role of water in crystallization of perovskite for the development of robust fabrication methods.
Moreover, perovskites can be a potential material for the electrolytes to improve the stability of batteries. Additionally, with an aim towards a sustainable future, lead-free perovskites have also emerged as an important material for battery applications as seen above.
Precisely, we focus on Li-ion batteries (LIBs), and their mechanism is explained in detail. Subsequently, we explore the integration of perovskites into LIBs. To date, among all types of rechargeable batteries, LIBs have emerged as the most efficient energy storage solution .
Because of the intrinsic ionic feature, the interactions between perovskites and water induce serious stability issues, which has been one of the fundamental problems hindering the practical application of perovskites.
As our current understanding stands, a suitable amount of water could be of help for growing high quality perovskite films due to the resultant formation of intermediates, such as MAPbI 3 ·H 2 O, which facilitates the conversion from precursors to perovskites.
The optimum power conversion efficiency (PCE) of devices increased to 22.13%, and preserved over 90% of the initial PCE during 29 d air aging (humidity: 60 ∼ 80 RH). This work overturns the popular concept of perovskite water stability, and provides a novel sight to improve the long-term stability of perovskite. 1. Introduction
Perovskite materials for highly efficient Photo(electro)catalytic water …
This is because PbI 2 has limited solubility in pure water (K sp = 4.4 × 10-9 at 20 °C). However, compounds such as PbI 3 − or PbI 4 2− would be formed under high I − concentration conditions. Using this approach makes it is possible to use HI to replace H 2 O as the reaction solution for the water splitting.
