Metal halide perovskite photovoltaics faces important challenges which hinder its tangible impact on the final applications, with performance and stability being critical limiting parameters. In this context, adjusting the perovskite grain boundaries and the crystalline surface becomes crucial tools to overcome these issues, improve optoelectrical devices' stability and performance to their theoretical limit, and extend the perovskite application range.
We present synthesis and passivation methods to fabricate device-oriented perovskite monocrystals in the macro and nanoscale. The working principle analysis, including electrical and optical techniques, displays how the optoelectrical response can be adjusted by controlling the crystal growth conditions and surface passivation, which can be linked to fundamental variations in the surface and bulk structure and composition.
