Inkjet printing processing conditions for bulk-heterojunction solar cells using two high-performing conjugated polymer donors
Hermerschmidt, F.; Papagiorgis, Panagiotis; Savva, Achilleas; Christodoulou, Chris C.; Itskos, Grigorios; Choulis, Stelios A. (2014)We report the processing conditions for inkjet-printed active layers of organic photovoltaic (OPV) devices comprising bulk-heterojunction blends of the low bandgap conjugated polymer poly[(4,4′-bis(2-ethylhexyl)dithieno[3,2-b: ...

Photovoltaic limitations of BODIPY:fullerene based bulk heterojunction solar cells
Baran, D.; Tuladhar, S.; Economopoulos, Solon P.; Neophytou, Marios; Savva, Achilleas; Itskos, Grigorios; Othonos, Andreas S.; Bradley, D. D. C.; Brabec, C. J.; Nelson, J.; Choulis, Stelios A. (2017)The photovoltaic performance of blends of a series of 4,4′-Difluoro-4-bora-3a,4a-diaza-s-indacenes)-based (BODIPY) conjugated polymers donors with fullerene electron acceptors is investigated. Despite the high Voc values ...
