Description

technical field

[0001] The present invention relates to an A-D-A conjugated molecule based on a dithienyl-indase unit as a core, an oligomerized five-membered aromatic heterocycle as a bridging unit, and an electron-withdrawing unit at the end, and a preparation method thereof, and the electron donor of this type of molecule as an active layer Applications of Bulk or Electron Acceptor Materials in Organic Solar Cells (OPVs). Background technique

[0002] Due to the advantages of low cost, light weight, bendability, solution processability and large area preparation, organic solar cells have received extensive attention in academia. In recent years, polymer and small molecule solar cells have developed rapidly and achieved remarkable results (X.Zhan, D.Zhu, Conjugated polymers for high-efficiency organic photovoltaics, Polym.Chem., 2010, 1,409; Y.Chen, X .Wan,G.Long,High performance photovoltaic applications using solution-processed small molecules,Acc.Chem.Res.,2013,46,2645...
