A theoretical calculation of the molecular parameters and construction of the spinodal phase diagrams highlight molecular incompatibilities between the donor and acceptor as a dominant mechanism for burn-in degradation, which is to date the major short-time loss reducing the performance and stability of organic solar cells.
Nature Communications 8, Article number: 14541 (2017) Cite this article The performance of organic solar cells is determined by the delicate, meticulously optimized bulk-heterojunction microstructure, which consists of finely mixed and relatively separated donor/acceptor regions.
The solar cells were completed by thermal evaporation of 15 nm MoOx and 100 nm Ag at 10 −6 mbar. All the J – V characteristics were recorded using a source measurement unit from BoTest.
