Organic photovoltaics (OPVs) have progressed steadily through three stages of photoactive
materials development:(i) use of poly (3-hexylthiophene) and fullerene-based acceptors …

Conspectus Over the past few years, the development of new materials has contributed to
rapid increases in the power conversion efficiencies (PCEs) of organic photovoltaic (OPV) …

Given that bromine possesses similar properties but extra merits of easily synthesizing and
polarizing comparing to homomorphic fluorine and chlorine, it is quite surprising very rare …

Despite the dihalogenation of terminals being an effective strategy to produce efficient
nonfullerene acceptor (NFA)-based organic solar cells (OSCs), hetero-dihalogenated …

Perovskite solar cells (PSCs) have achieved power conversion efficiencies (PCEs)
exceeding 25% over the past decade and effective passivation for the interface with high …

Fused‐ring electron acceptors have made significant progress in recent years, while the
development of fully non‐fused ring acceptors has been unsatisfactory. Here, two fully non …

As a common feature in a majority of malignant tumors, hypoxia has become the Achilles'
heel of photodynamic therapy (PDT). The development of type‐I photosensitizers that show …

To elevate the performance of polymer solar cells (PSC) processed by non‐halogenated
solvents, a dissymmetric fused‐ring acceptor BTIC‐2Cl‐γCF3 with chlorine and …

Trifluoromethylation has been used for nonfullerene acceptors, resulting in an ultra-narrow
band-gap molecule named BTIC-CF 3-γ. Compared to its fluorinated and chlorinated …

The power conversion efficiency of organic solar cell (OSC) devices has surpassed 18%
rapidly. In order to further promote OSC development, it is necessary to understand the …
