Abstract
Chalcogen-substituted PCBM derivatives are a promising approach to enhance power efficiency in ternary organic solar cells (TOSCs).
Highlights
Ternary organic solar cells (TOSCs) are a promising approach to enhance the power conversion efficiency in organic-based solar cells
Thereby, we focused on the design and synthesis of PCBM derivatives compatible with the molecular structure of PM6 and Y6 capable of improving the charge generation and extraction of PM6:Y6 to obtain more efficient TOSCs
To expand the study about the influence of sulphur in ternary organic solar cells to other chalcogens, in this study, we report the synthesis and characterization of PCBM substituted with furan (PCBFu), thiophene (PCBTh) or selenophene (PCBSe) as the third component in TOSCs based on PM6:Y6
Summary
Ternary organic solar cells (TOSCs) are a promising approach to enhance the power conversion efficiency in organic-based solar cells. Except PCBFu, have a lower leakage current than the binary one suggesting a decrease of charge recombination.[36] In addition, the dark J–V curves of TOSCs based on PCBM, PCBTh and PCBSe exhibited similar behaviour in the forward bias.
