The ROLA-FLEX article was published open access at Applied Physics Letters.
In this paper RoLA-Flex partners (Cyprus University of Technology and AVANTAMA) show that a solution processable Sb-doped SnO2 (ATO) metal oxide ink processed on the top of the PM6:Y6:PC70BM non-fullerene acceptor (NFA) organic active layer by doctor-blading exhibits exceptional, wetting properties, electrical conductivity, optical transmittance and hole charge carrier selectivity which are critical parameters for high performance solution processed hole transporting layers (HTL) in inverted organic photovoltaics (OPVs). Inverted OPVs implementation using PM6:Y6:PC70BM active layer reveals that 130 nm solution processed ATO HTL provides similar power conversion efficiency and light stability to that achieved with the commonly used thermally evaporated MoO3 HTL.
