Three hexapod-shaped PDI-hexamers (PSM1, PSM2, and PSM3) with a diphenylmethylene-
bridged triphenylamine (TPA) core and six peripheral PDI subunits have been designed and …

A systematic approach for assessing organic photovoltaic (OPV) materials for large scale
production based on the efficiency, lifetime and cost has been developed. These parameters …

Solution-based organic solar cells (OSCs) offer great potential prospects within low-cost
electricity production. High-performance materials are traditionally low bandgap polymers …

The mechanism of how the solvent type influences photovoltaic performance and thermal
stability of non-fullerene organic solar cells remains unexplored. In this article, the well …

Photovoltaics is a portentous alternative to the nonrenewable energy resources. Organic
solar cells (OSCs) offer several advantages over inorganic counterparts in terms of low-cost …

A spiro [fluorene-9, 9′-xanthene], often described as a “low-cost spiro,” has been
functionalized with terminal diketopyrrolopyrrole units to generate a promising, three …

One of the puzzles in the field of organic photovoltaic cells (OPVs) is the high exciton
dissociation (charge generation) efficiency even though simple Coulomb based arguments …

One-dimensional ladder-type nonfullerene electron acceptors (NFAs) with large fused ring
cores have been widely used in highly efficient organic solar cells (OSCs). Recent studies …

In this study, carbon nanotubes (CNTs) are packed to prepare CNT films with chemical‐
vapor‐deposition method and vacuum filtration, then the films are piled up to make …

Panchromatic molecules, eg organic small molecules with wide absorption spectra, are very
desirable for solar energy‐related applications. Here, we report the development of a series …
