TLDR
In this paper, a new material, water stable haloplumbate (TBA)PbI3, is proposed for interfacial modification, which is formed on the perovskite surface in-situ by tetra-butylammonium iodide(TBAI) treatment.Abstract:
The commercialization
of perovskite solar cells is mainly limited by their operational stability. Interlayer
modification by thin interface materials between the perovskite and the charge
transport layers is one of the most effective methods to promote the efficiency
and stability of perovskite devices. However, the commonly used interlayer
materials do not meet all the demands, including good film quality, excellent
stability, and passivation capability without interfering with the charge transport.
In
this work, we propose a new material, water stable haloplumbate [TBA]PbI3
for interfacial modification, which is formed on the perovskite surface in-situ by tetra-butylammonium iodide
(TBAI) treatment. Benefiting from its passivation effect and
robustness, the modified devices result in a power conversion efficiency of 22.90%
with excellent environmental and operational stability.read more

TL;DR: In this paper, a self-formed PbI2-dimethyl sulfoxide adduct was used for fabricating a high quality perovskite film, and the results showed that a larger grain size and excessive lead iodide in the film effectively suppress carrier recombination, which is helpful to improve the device stability and efficiency.
