Abstract:Uniform optoelectronic quality of metal halide perovskite
(MHP)
films is critical for scalable production in large-area applications,
such as photovoltaics and displays. While vapor-based MHP film deposition
is advantageous for this purpose, achieving film uniformity can be
challenging due to uneven temperature distribution and precursor concentration
over the substrate. Here, we propose optimized substrate orientations
for the vapor-based fabrication of homogeneous MAPbI3 thin
films, involving a PbI2 primary … Show more
