As
the market of the Internet of Things (IoT) increases, great
attention has been paid to the development of high-efficient organic
photovoltaics (OPVs) utilizing artificial light. However, in a real
indoor condition, the power density contribution of the artificial
light cannot exceed 35% in the combination of indoor and outdoor irradiation,
which indicates that the illumination of sunlight cannot be ignored
during daytime. Hence, it is urgent to develop high-efficient OPVs
in indoor conditions taking into account both sunlight and artificial
light. In this work, a novel asymmetric molecule TB-4F was synthesized
to trade-off the absorption spectrum that can be applied under both
artificial light and sunlight. In conventional bulk-heterojunction
(C-BHJ), it was figured out that due to nonoptimal morphology some
carriers failed to be efficiently collected. Herein, a sequential
deposition bulk-heterojunction (SD-BHJ) as an alternative fabrication
method successfully enhanced the performance of OPVs, under both artificial
light and sunlight, which was attributed to the favorable microstructure
being vertically distributed in the active layer. Notably, the PCE
was significantly increased by 25% for SD-BHJ compared to C-BHJ under
artificial light, owing to the strong effect of trap-assisted recombination
and dark current on PCE in the condition of low carrier density. Our
result indicates that an asymmetric molecule with a blue-shifted spectrum
fabricated by SD-BHJ can be a promising candidate that can be applied
in indoor environments to harvest sunlight and artificial light simultaneously.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
