dc.description.abstract | A series of low bandgap copolymers composed of N-acyl-substituted dithieno[3,2-b:2′,3′-d]pyrroles (DTPs) as the electron rich donor constituents (with various alkyl side chain patterns) combined with different electron deficient acceptor building blocks are developed for polymer solar cell applications. Due to the introduction of the N-acyl substituents, the HOMO energy levels of the push–pull copolymers decrease as compared to the N-alkyl-DTP analogues, resulting in an increased open-circuit voltage (Voc) and hence solar cell performance. For an N-acyl-DTP-alt-thieno[3,4-c]pyrrole-4,6-dione (PDTP-TPD) copolymer a bulk heterojunction device with a Voc up to 0.80 V and a power conversion efficiency of 4.0% is obtained, the highest value for DTP-based polymer materials to date. Moreover, by implementation of a conjugated polyelectrolyte cathode interlayer the short-circuit current noticeably increases, enhancing the solar cell efficiency to 5.8%. | - |

The authors further thank BELSPO for funding the IAP 7/05 network. The reported activity is partly supported by the project ORGANEXT (EMR.INT4-1.2.-2009-04/054), selected in the frame of the operational program INTERREG IV-A Euregio Maas-Rijn. The FWO (Research Foundation Flanders) and SIM (Strategisch Initiatief Materialen vzw) are acknowledged for the M.ERA-NET project "RADESOL" (GA.013.13N) and the program "Solution based Processing of Photovoltaic Modules" (SoPPoM, GA no. 2010-01, including the projects OPvTECH and absCIGS), respectively. V.L. thanks the F.R.S.-FNRS for his Research Associate position. The calculations were performed on the computing facilities of the Consortium des Equipements de Calcul Intensif (CECI), in particular those of the Plateforme Technologique de Calcul Intensif (PTCI) installed in the University of Namur, for which the authors acknowledge financial support of the FNRS-FRFC (Convention no. 2.4.617.07.F and 2.5020.11) and the University of Namur. We also acknowledge Hercules for providing the funding for the LTQ Orbitrap Velos Pro mass spectrometer. | - |
