DOIAbstract
International audienceWe describe an efficient synthetic route toward novel organocobalt complexes [([small eta]4-C4(nT)4)Co([small eta]5-C5H5)] with n = 1, 2, 3 thiophene rings. Solution-processed bulk heterojunctions solar cells based on CpCoCb(3T)4:PCBM blends achieve power conversion efficiencies of up to 2.1%
