Journal ArticleDOI
2.5% efficient organic plastic solar cells
Sean E. Shaheen,Christoph J. Brabec,N. Serdar Sariciftci,F. Padinger,Thomas Fromherz,Jan C. Hummelen +5 more
TL;DR: In this article, the power conversion efficiency of organic photovoltaic devices based on a conjugated polymer/methanofullerene blend is dramatically affected by molecular morphology.
Journal ArticleDOI
Origin of the Open Circuit Voltage of Plastic Solar Cells
Christoph J. Brabec,Antonio Cravino,Dieter Meissner,Niyazi Serdar Sariciftci,Thomas Fromherz,Minze T. Rispens,Luis Sánchez,Jan C. Hummelen +7 more
TL;DR: A series of highly soluble fullerene derivatives with varying acceptor strengths (i.e., first reduction potentials) was synthesized and used as electron acceptors in plastic solar cells as discussed by the authors.
Journal ArticleDOI
CMOS-compatible graphene photodetector covering all optical communication bands
Andreas Pospischil,Markus Humer,Marco M. Furchi,Dominic Bachmann,Romain Guider,Thomas Fromherz,Thomas Mueller +6 more
TL;DR: In this article, a CMOS-compatible photodetector based on graphene with multi-gigahertz operation ranging from the O-to U-band of telecommunication bands is demonstrated, highlighting the promise of graphene as a new material for integrated photonics.
Journal ArticleDOI
Temperature dependence for the photovoltaic device parameters of polymer-fullerene solar cells under operating conditions
Eugene A. Katz,David Faiman,Sachetan M. Tuladhar,Jan M. Kroon,MM Martijn Wienk,Thomas Fromherz,F. Padinger,Christoph J. Brabec,Niyazi Serdar Sariciftci +8 more
TL;DR: In this paper, the temperature dependence of various photovoltaic device parameters of solar cells, fabricated from interpenetrating networks of conjugated polymers with fullerenes, in the wide temperature range of their possible operating conditions was reported.
Journal ArticleDOI
Angle dependence of external and internal quantum efficiencies in bulk-heterojunction organic solar cells
Gilles Dennler,Karen Forberich,Markus C. Scharber,Christoph J. Brabec,Igor Tomiš,Kurt Hingerl,Thomas Fromherz +6 more
TL;DR: In this article, the optical properties of poly(3-hexylthiophene): 1-(3-methoxy-carbonyl) propyl-1-phenyl[6,6]C61 based solar cells with two different thicknesses of the active layer (170 and 880nm) were investigated, and it was shown that in the thin ones the absorption is enhanced for oblique incident radiation.
