Implication

Materials study demonstrates thick-film polymer solar cells reaching 10.8% efficiency across multiple material combinations, indicating enhanced design flexibility for organic photovoltaics.

Key Points

To overcome material combination constraints in polymer solar cells by manipulating polymer aggregation to create an optimal active-layer morphology.
Regulated the temperature-dependent aggregation behaviour of donor polymers blended with fullerene acceptors.
Fabricated thick-film solar cell devices containing crystalline, nanoscale polymer domains across multiple donor:fullerene material pairings.
Achieved power conversion efficiencies up to 10.8% and fill factors up to 77% in thick-film polymer solar cells.
Developed three donor polymers exhibiting efficiencies greater than 10%, with morphology formation remaining insensitive to fullerene choice.
