Stereomeric effects of bisPC71BM on polymer solar cell performance
Two stereomers of bisadduct analogues of [6, 6]-phenyl-C71-butyric acid methyl ester (bisPC71BM) were synthesized and their geometrical structures with cis- or trans-configuration were identified by X-ray crystal...

Theoretical insight into the stereometric effect of bisPC71BM on polymer cell performance
It has been experimentally demonstrated that the stereometric packings of two new bisPC71BM isomers have an important impact on the power conversion efficiency of organic solar cells. Here, a theoretical investig...
