To identify criteria for processing additives that control material morphology and improve the performance of bulk heterojunction solar cells.
Evaluated the 1,8-di(R)octane class of chemical additives with various functional groups based on selective fullerene solubility and a boiling point higher than the host solvent.
Fabricated and tested bulk heterojunction solar cells with and without processing additives to measure morphological control and photovoltaic efficiency.
Selective solubility of the fullerene component via high boiling point processing additives successfully controlled bulk heterojunction morphology, with the iodine functional group (R = I) performing best.
Incorporating 1,8-diiodooctane as the processing additive increased the power conversion efficiency of the bulk heterojunction solar cells from 3.4% in the reference device to 5.1%.
