Journal ArticleDOI
Polymer photovoltaic cells : enhanced efficiencies via a network of internal donor-acceptor heterojunctions
TL;DR: In this paper, the carrier collection efficiency and energy conversion efficiency of polymer photovoltaic cells were improved by blending of the semiconducting polymer with C60 or its functionalized derivatives.
Journal ArticleDOI
Plastic Solar Cells
TL;DR: In this article, the photo-induced electron transfer leads to a number of potentially interesting applications, which include sensitization of the photoconductivity and photovoltaic phenomena, and their potential in terrestrial solar energy conversion discussed.
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
Preparation and Characterization of Fulleroid and Methanofullerene Derivatives
TL;DR: In this paper, the synthesis and complete characterization of soluble derivatives of C-60 for applications to physics and biology was described, where the goal of the strategy was to have a "modular" approach in order to be able to easily vary a functional group attached indirectly to the cluster.
