Suppressing pre-aggregation to increase polymer solar cell ink shelf life
Wang, Z., Peng, Z., Balar, N., & Ade, H. (2023, November 2). JOURNAL OF MATERIALS CHEMISTRY A.
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.
