Novel solvent recipe boosts efficiency of organic solar cells

In a study recently published in the Chemical Engineering Journal, a research team from National Taiwan University and international collaborators have developed a straightforward solvent-mixing strategy to significantly boost the performance of next-generation all-polymer organic solar cells. By adding a small fraction of a cosolvent during fabrication, the team successfully resolved a long-standing challenge in controlling film quality, opening new possibilities for commercializing flexible, e
