| Abstract | Two novel indacenodithiophene (IDT) based donor-acceptor (D-A) narrow band-gap polymers PIDTBDTID and PIDTBDT(ID)(2) were designed and synthesized, where one/two isoindigo (ID) moieties were introduced into the backbone as the acceptor unit. The optical, thermal, electrochemical and photovoltaic properties have been investigated in detail. The PIDTBDTID containing one ID unit exhibited better light-harvesting properties and charge transport properties. On the other hand, the PIDTBDT(ID)(2) with two ID units displayed lower the highest occupied molecular orbital energy levels (HOMO). Using these polymers as electron donors and (6,6)-phenyl-C-71-butyric acid methyl ester (PC71BM) as electron acceptor, polymer solar cells (PSCs) based on PIDTBDTID exhibited better photovoltaic performance with a power conversion efficiency (PCE) of 2.66%, an open-circuit voltage (V-oc) of 0.87 V and an enhanced short-circuit current (J(sc)) of 7.24 mA cm(-2). While the PIDTBDT(ID)(2)-based PSCs shown a PCE of 2.50%, an improved V-oc of 0.93 V and an J(sc) of 6.34 mA cm(-2). (C) 2016 Elsevier Ltd. All rights reserved. |
