Journal ArticleDOI

The comprehensive utilization of the synergistic effect of fullerene and non-fullerene acceptors to achieve highly efficient polymer solar cells

TL;DR: In this paper, a ternary PSC based on PTBTz-2:IT-M:PC71BM with different weight ratios was systematically investigated, and the energy transfer mechanism between PC71BM and IT-M was investigated in depth by femtosecond pump-probe transient absorption spectroscopy and time correlated single-photon counting.
Journal ArticleDOI

Enhanced efficiency of polymer solar cells through synergistic optimization of mobility and tuning donor alloys by adding high-mobility conjugated polymers

TL;DR: In this paper, a diketopyrrolopyrrole-based small bandgap polymer (DPPT-TT) with high mobility is introduced as an additive to D-A1-D-A2 type thieno[3,4-b]thiophene-based random copolymer (P3):(6,6)-phenyl-C70-butyric acid methyl ester (PC71BM) polymer solar cells (PSCs) were improved from 615% to 830% with the addition of 05% DPPT
Journal ArticleDOI

Self-doping n-type polymer as a cathode interface layer enables efficient organic solar cells by increasing built-in electric field and boosting interface contact

TL;DR: In this paper, a self-doping polymer cathode interface material for organic solar cells was synthesized by incorporating benzotriazole (BTA) as an electron-deficient group and a fluorene containing an amino group.
Journal ArticleDOI

Enhanced Organic Photovoltaic Performance through Modulating Vertical Composition Distribution and Promoting Crystallinity of the Photoactive Layer by Diphenyl Sulfide Additives.

TL;DR: DPS could not only modulate the vertical composition distribution but also promote the ordered molecular packing of the photoactive layer, thus effectively improving exciton dissociation, charge transport, and collection, and thus exhibit an excellent power conversion efficiency after using 3% DPS additive.
