TL;DR: In this article , surface treatments may induce a negative work function shift (that is, more n-type), which activates halide migration to aggravate PSC instability, limiting the maximum stability improvement attainable for PSCs treated in this way.

TL;DR: A hole-transporting large-bandgap polymer (poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine (PTAA)) is employed to partially replace polymer donors in the active layer of PBDB-T/Y1, and semitransparent OPVs with PCEs of 12% and AVTs of 20% are achieved, both on rigid and flexible substrates.

TL;DR: To ensure sufficient photogenerated holes in the rear subcell, a small amount of an infrared-absorbing polymer donor as a third component is introduced, which provides a second hole-generation and transporting mechanism to minimize the aforementioned detrimental effects.

TL;DR: In this paper, important studies of semitransparent organic solar cells for agricultural applications are reviewed and the design routes and strategies are summarized, and the perspectives for the future research on agricultural photovoltaics are also presented.

TL;DR: In this paper , the structure-property relationship in the design of perovskite solar cells (PSCs) has been analyzed and compared on a molecular level, which will serve as a comprehensive reference to molecular design guidelines for various types of OCTMs.
