Congratulations to Christian B. Nielsen at el.for being awarded VIP status on their Advanced Materials #paper
Congratulation to Christian, Shahid, Neil, Bob, Jenny, Andrew, Natalie and Iain for their publication on "2,1,3-Benzothiadiazole-5,6-Dicarboxylic Imide - A Versatile Building Block for Additive- and Annealing-Free Processing of Organic Solar Cells with Efficiencies Exceeding 8%" in Advanced Materials.
Abstract:
A new photoactive polymer comprising benzo[1,2-b:3,4-b′:5,6-d′]trithiophene and 2,1,3-benzothiadiazole-5,6-dicarboxylic imide is reported. The synthetic design allows for alkyl chains to be introduced on both electron-rich and electron-deficient components, which in turn allows for rapid optimization of the alkyl chain substitution pattern. Consequently, the optimized polymer shows a maximum efficiency of 8.3% in organic photovoltaic devices processed in commercially viable fashion without solvent additives, annealing, or device engineering.
