We describe an all-polymeric PBQx-TF/D18/PY-IT-based organic photovoltaic device that achieves balanced charge transport and suppressed charge recombination, exhibiting excellent thermal stability with a T80 of 1530 hours at 120 °C.
Pincer-shaped non-covalent bond interactions are introduced between a small-molecule additive and polymer acceptor, effectively improving the photovoltaic performance and mechanical stability of all-polymer solar cells.
By designing new terpolymers, we tuned the molecular orientation to obtain an ordered morphology with suppressed energetic disorder. Thus, we boost the PCE of all-PSCs to over 18%.
Additive assisted strategies play a crucial role in optimizing the morphology and improving the performance of organic solar cells (OSCs), yet the molecular-level mechanisms remain unclear.
A low-cost wide-bandgap acceptor FPCC-Br was designed which exhibited a champion PCE of 13.6% in OPV cells below 720 nm and demonstrated significant advantages in indoor lighting, tandem cells, and underwater photovoltaic electrolysis applications.
