Manipulation of PBDT-DTNT:PCBM photoactive layers for a stability increment by core–shell and core–mantle–shell supramolecules

Two types of core–shell and core–mantle–shell supramolecules were designed based on grafted-CNTs and PBDT-DTNT chains and employed in the active layers of PBDT-DTNT:PC₇₁BM solar cells to stabilize morphology and performance.
