| Abstract | A new viologen derivative namely 1,1’-bis(3,4-dihydroxybutyl)-[4,4’-bipyridine]-1,1’-diium bromide (V-Pr-2OH) was synthesized and applied as a cathode buffer layer to inverted polymer solar cells (PSCs) based on the blend of PTB7 : PC71BM. PSCs with the structure of ITO/V-Pr-2OH/PTB7 : PC71BM/MoO3/Ag as the cathode buffer layer showed the power conversion efficiency (PCE) up to 7.28%, which is comparable to that of the PSCs with the structure of ITO/ZnO/PTB7 : PC71BM/MoO3/Ag (7.44%) in the absence of V-Pr-2OH. This study demonstrates that a highly efficient PSCs without any high temperature heat treatment can be obtained. |
