Energy level alignment at interfaces in organic photovoltaic devices

Andreas Opitz, +5 more
- 01 Oct 2013 - 
TL;DR: The alignment of energy levels at interfaces in organic photovoltaic devices is crucial for their energy conversion efficiency as mentioned in this paper, and general considerations for correlating the electronic structure and performance of devices are discussed.
Journal ArticleDOI

Unraveling the Microstructure of Molecularly Doped Poly(3-hexylthiophene) by Thermally Induced Dedoping

Hannes Hase, +5 more
- 25 Oct 2018 - 
TL;DR: In this article, thermal annealing of poly(3-hexylthiophene) (P3HT) molecularly p-doped with the strong electron acceptor 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) was exploited as a tool for tuning the doping concentration as a quasi singular parameter.
Journal ArticleDOI

Rove beetles of the subtribe Scopaeina Mulsant & Rey (Coleoptera: Staphylinidae) in the West Palaearctic: Phylogeny, biogeography and species catalogue

Johannes Frisch, +2 more
- 01 Jan 2002 - 
TL;DR: Results show that Scopaeina comprises two well-supported monophyletic groups in the West Palaearctic, Micranops Cameron, 1913 and Scopaeus Erichson, 1840, which are considered to represent distinct genera.
Journal ArticleDOI

Effect of molecular electrical doping on polyfuran based photovoltaic cells

Shuwen Yu, +6 more
- 20 May 2015 - 
TL;DR: In this paper, the electronic, optical, and morphological properties of molecularly p-doped polyfuran (PF) films were investigated over a wide range of doping ratio in order to explore the impact of doping in photovoltaic applications.
Journal ArticleDOI
