Symmetry breaking provides a new material design strategy for nonfullerene small molecule
acceptors (SMAs). The past 10 years have witnessed significant advances in asymmetric …

Semitransparent organic solar cells (ST-OSCs) have attracted attention for use in building
integrated photovoltaics because of their large range tunability in colors, transparency, and …

This work summarizes recent developments in polymer solar cells (PSCs) prepared by a
chlorination strategy. The intrinsic property of chlorine atoms, the progress of chlorinated …

Owing to the advantages of broad absorption, semitransparency, and largearea solution
processing, organic solar cells based on a nonfullerene blend system have attracted wide …

Morphology control in laboratory and industry setting remains as a major challenge for
organic solar cells (OSCs) due to the difference in film-drying kinetics between spin coating …

The rapid development of low-bandgap (LBG) nonfullerene acceptors and wide-bandgap
(WBG) copolymer donors in recent years has boosted the power conversion efficiency (PCE) …

Compared with inorganic or perovskite solar cells, the relatively large non‐radiative
recombination voltage losses (ΔVnon‐rad) in organic solar cells (OSCs) limit the …

While great progress has been achieved in all-polymer solar cells (all-PSCs), the efficiency
of all-PSCs is primarily limited by polymer acceptors that lack a high extinction coefficient …

Donor halogenation is a common molecular design strategy used to reduce voltage losses
(ΔVloss) and improve the power conversion efficiency (PCE) of bulk-heterojunction (BHJ) …

At present, most of the top-performing organic solar cells (OSCs) are processed with high
boiling point solvent additives, which usually have a negative effect on the device stability …
