Organic Solar Cells, Conjugated Polymers, and Non-Fullerene Acceptors
This community develops organic photovoltaic devices, focusing on the molecular design of active layers and charge transport mechanisms to convert light into electricity.
The research centers on the synthesis and optimization of conjugated polymers and small-molecule acceptors, particularly non-fullerene acceptors, for use in bulk heterojunction and inverted device architectures. Recurring themes include the engineering of donor-acceptor interfaces, the modulation of charge transport layers, and the reduction of non-radiative recombination losses. The work involves the creation of thin films with specific morphologies, such as fibrils or hierarchical structures, to enhance efficiency and stability. Applications extend to flexible, stretchable, and semitransparent solar cells, as well as organic photodetectors. The materials studied include fluorinated acceptors, zwitterionic interlayers, and conductive polymers, with a strong emphasis on molecular design strategies like core halogenation and side-chain engineering.
The largest share of the community's output is found in tin research, accounting for 1.6% of all tin research, and indium research, accounting for 1.7% of all indium research.
The community comprises 14,182 papers, published primarily in Organic Electronics, Applied Physics Letters, and ACS Applied Materials & Interfaces.
Recent work focuses on achieving efficiencies exceeding 20% in binary and tandem organic solar cells through advanced molecular design, such as narrow-bandgap acceptors and solid additive engineering, as well as the development of scalable polymers for large-area semitransparent applications.
