Multifunctional interface engineering enables efficient and stable inverted organic photovoltaics

Compared to conventional (p-i-n) organic photovoltaics (OPVs), inverted (n-i-p) OPVs hold promise for future commercial applications due to their advantages in printing process compatibility and environment robustness. The current bottleneck lies in the efficiency and light stability, which is closely related to the defects and the photocatalytic reactivity of metal oxides transport layer. This comment summarizes the recent progress on inverted OPV and outlines potential solutions to surmount the hurdles before the technology can be put into production. The efficiency and light stability of inverted organic photovoltaics have been limited by the defects and photocatalytic reactivity of metal oxides transport layer. Here, authors discuss the recent progress and potential solutions for this technology to be put into production and industrialization.
