It has been commonly believed that the driving force at the donor-acceptor heterojunction is vital to efficient charge separation in organic solar cells. Here Zhong et al. show that the driving force can be as small as 0.05 eV without compromising th

P92 steels (9 Cr – 0.5 Mo – 1.8 W) are one of the candidate materials for Ultra Super Critical (USC) power plants. Since normalization of P92 results in the formation of martensitic microstructure, the steel is generally used in the normalized an

Short Excited State Lifetimes Mediate Charge Recombination Losses in Organic Solar Cell Blends with Low Charge Transfer Driving Force. Advanced materials, 34(22), p. 2101784. Wiley-VCH 10.1002/adma.202101784
A blend of a low-optical-gap diketopyrrolopyrrole polymer and a fullerene derivative, with near-zero driving force for electron transfer, is investigated. Using femtosecond transient absorption and electroabsorption spectroscopy, the charge transfer
