Molecular engineering of the core part of D–π–A–π–D based small acceptor molecules for efficient organic solar cells: a DFT approach

Abstract

Here, five new donor-$\pi$-acceptor-$\pi$-donor (D-$\pi$-A-$\pi$-D) type conjugated acceptors have been designed by incorporating quinacridone as the donor unit, thiophene as the common $\pi$-bridging unit, and five central acceptor units. To...
