End group modulation of A–D–A type small donor molecules for DTP based organic photovoltaic solar cells: a DFT approach
Smiti Rani Bora, Dhruba Jyoti Kalita
Abstract
Here, five new acceptor–donor–acceptor (A–D–A) type small donor molecules C1–C5, have been designed based on the central D unit, dithieno[3,2- b :2′,3′- d ]pyrrole (DTP).
