Room-Temperature Processing of Inorganic Perovskite Films to Enable Flexible Solar Cells
Inorganic lead halide perovskite materials have attracted great attention
recently due to their potential for greater thermal stability compared to
hybrid organic perovskites. However, the high processing temperature to convert
from the non-perovskite phase to cubic perovskite phase in many of these
systems has limited their application in flexible optoelectronic devices. Here,
we report a room temperature processed inorganic PSC based on CsPbI2Br as the
light harvesting layer. By combing this composition with key precursor
solvents, we show that the inorganic perovskite film can be prepared by the
vacuum-assist method under room temperature conditions in air. Unencapsulated
devices achieved the power conversion efficiency up to 8.67% when measured
under 1-sun irradiation. Exploiting this room temperature process, flexible
inorganic PSCs based on an inorganic metal halide perovskite material is
demonstrated.Comment: 23 pages, 4 figures, and supplemental informatio
