Journal ArticleDOI
Nanoscale Morphology of High-Performance Polymer Solar Cells
Xiaoniu Yang,J Joachim Loos,Sjoerd Veenstra,Wiljan Verhees,MM Martijn Wienk,Jan M. Kroon,Matthias A. J. Michels,René A. J. Janssen +7 more
TL;DR: Both the improved crystalline nature of films and increased but controlled demixing between the two constitutes therein after annealing explains the considerable increase of the power conversion efficiency observed in these devices.
Journal ArticleDOI
High-performance polymer solar cells of an alternating polyfluorene copolymer and a fullerene derivative
Mattias Svensson,Fengling Zhang,Sjoerd Veenstra,Wiljan Verhees,Jan C. Hummelen,Jan M. Kroon,Olle Inganäs,Mats Andersson +7 more
TL;DR: In this paper, the alternating copolymer with a C-60 derivative (PCBM) was used for solar cells with a power conversion efficiency of 2.2 % under simulated solar light.
Journal ArticleDOI

TL;DR: A consensus between researchers in the field is reported on procedures for testing perovskite solar cell stability, which are based on the International Summit on Organic Photovoltaic Stability (ISOS) protocols, and additional procedures to account for properties specific to PSCs are proposed.
Journal ArticleDOI
Fullerene bisadducts for enhanced open-circuit voltages and efficiencies in polymer solar cells
Martijn Lenes,Gert-Jan A. H. Wetzelaer,Floris B. Kooistra,Sjoerd Veenstra,Jan C. Hummelen,Paul W. M. Blom +5 more
TL;DR: In this article, a bisadduct was proposed to enhance the efficiency of poly(3-hexylthiophene) and poly(6,6]-phenyl C-61 butyric acid methyl ester (PCBM) solar cells.
Journal ArticleDOI
Compositional and Electric Field Dependence of the Dissociation of Charge Transfer Excitons in Alternating Polyfluorene Copolymer/Fullerene Blends
Dirk Veldman,Özlem Ipek,Stefan C. J. Meskers,Jörgen Sweelssen,Marc M. Koetse,Sjoerd Veenstra,Jan M. Kroon,SS Svetlana van Bavel,J Joachim Loos,René A. J. Janssen +9 more
TL;DR: The electro-optical properties of thin films of electron donor-acceptor blends of a fluorene copolymer and a fullerene derivative were studied and it is shown that in these films nanocrystalline PCBM clusters are formed at high PCBM content.
