Modification on the Indacenodithieno [3,2
Modification on the indacenodithieno[3,2-b]thiophene (IT) core was used in the central phenyl moiety to explore efficient fused-ring acceptors (FRAs). By replacing two free H atoms with weak and small electron-donating methyl or methoxy groups, two novel IT-4F series FRAs named IM-4F and IOM-4F have been designed. The systematical study is …
A detailed study on loss processes in solar cells
