• 2015

Recent years have seen considerable advances in organic photovoltaics (OPVs), most notably a significant increase in their efficiency, from around 4 % to over 10 %. The stability of these devices,… (More)

High-Performance Inverted Organic Photovoltaics Without Hole-Selective Contact

• Achilleas Savva, Ignasi Burgués-Ceballos, Giannis Papazoglou, Stelios A Choulis
• ACS applied materials & interfaces
• 2015

A detailed investigation of the functionality of inverted organic photovoltaics (OPVs) using bare Ag contacts as the top electrode is presented. The inverted OPVs without a hole-transporting layer… (More)

Linking the HOMO-LUMO gap to torsional disorder in P3HT/PCBM blends.

• The Journal of chemical physics
• 2015

The electronic structure of [6,6]-phenyl C61 butyric acid methyl ester (PCBM), poly(3-hexylthiophene) (P3HT), and P3HT/PCBM blends is studied using soft X-ray emission and absorption spectroscopy and… (More)

Influence of the Hole Transporting Layer on the Thermal Stability of Inverted Organic Photovoltaics Using Accelerated-Heat Lifetime Protocols

• Felix Hermerschmidt, Achilleas Savva, +7 authors Stelios A Choulis
• ACS applied materials & interfaces
• 2017

High power conversion efficiency (PCE) inverted organic photovoltaics (OPVs) usually use thermally evaporated MoO3 as a hole transporting layer (HTL). Despite the high PCE values reported, stability… (More)
