Perovskite Single-Crystal Microarrays for Efficient
Photovoltaic Devices
Posted on 2018-07-11 - 18:23
Hybrid perovskite single crystals
offer a great promise for optoelectronic
devices, and patterning is broadly required in industrialized applications
for functional purposes. However, established patterning techniques
meet their limitations when it comes to hybrid perovskite single crystals
with multilayered diode structures. In this work, an Ostwald ripening
assisted photolithography (ORAP) patterning process, which employs
wettability-assisted blade-coating and Ostwald ripening assisted crystallization,
is developed for fabricating patterned perovskite single-crystal microarrays.
Optoelectronic devices based on uniform perovskite single-crystal
microarrays with a multilayered diode structure can be constructed
through the ORAP process. To demonstrate the compatibility of the
ORAP process with the manufacture of optoelectronic devices, patterned
CH3NH3PbBr3 single-crystal
microarray solar cells, which show enhanced performance than solar
cells based on CH3NH3PbBr3 continuous
single crystals reported, were fabricated. With the development of
perovskite research, we are confident that the ORAP process opens
a new avenue to fabricate optoelectronic devices based on perovskite
microarrays.
