An Ink‐Composition Engineering Approach for Upscaling of Organic Solar Cells with High‐Efficiency Retention Factor
Journal ArticleDOI
Impact of the Electron Acceptor Nature on the Durability and Nanomorphological Stability of Bulk Heterojunction Active Layers for Organic Solar Cells.
TL;DR: Fullerene OSCs may be the best currently available choice for unencapsulated room temperature applications but if oxidation of the polymer acceptors can be avoided, all polymer active layers should enable the fabrication of highly durable Oscs with lifetimes matching the requirements for OSC commercialization.
