Suppressing pre-aggregation to increase polymer solar cell ink shelf life

An approach to slow down the polymer solar cell ink aging by employing an additive (i.e., PCBM variants) was developed. It is inferred that PCBMs in the ink act as a co-solvent and slow down the polymer pre-aggregation.

Additive-free molecular acceptor organic solar cells processed from a biorenewable solvent approaching 15% efficiency

We report on the use of molecular acceptors and donor polymers processed with a biomass-derived solvent 2-methyltetrahydrofuran to facilitate bulk heterojunction organic photovoltaics with power conversion efficiency approaching 15%.
