Journal ArticleDOI
High-performance semitransparent perovskite solar cells with solution-processed silver nanowires as top electrodes
Fei Guo,Hamed Azimi,Yi Hou,Thomas Przybilla,Mengyao Hu,Carina Bronnbauer,Stefan Langner,Erdmann Spiecker,Karen Forberich,Christoph J. Brabec +9 more
TL;DR: A thin layer of zinc oxide nanoparticles is introduced beneath the Ag NWs, which fulfills two essential functionalities: it ensures ohmic contact between the PC60BM and the AgNWs and it serves as a physical foundation that enables the solution-deposition of AgNWS without causing damage to the underlying perovskite.
Journal ArticleDOI
Abnormal strong burn-in degradation of highly efficient polymer solar cells caused by spinodal donor-acceptor demixing.
Ning Li,José Darío Perea,Thaer Kassar,Moses Richter,Thomas Heumueller,Gebhard J. Matt,Yi Hou,Nusret S. Güldal,Haiwei Chen,Shi Chen,Stefan Langner,Marvin Berlinghof,Tobias Unruh,Christoph J. Brabec +13 more
TL;DR: An abnormal strong burn-in degradation in highly efficient polymer solar cells is demonstrated caused by spinodal demixing of the donor and acceptor phases, which dramatically reduces charge generation and can be attributed to the inherently low miscibility of both materials.
Journal ArticleDOI
Determination of the P3HT:PCBM solubility parameters via a binary solvent gradient method: Impact of solubility on the photovoltaic performance
TL;DR: In this paper, an alternative route to determine the solubility parameters of two prototype organic semiconductors, namely the semi-crystalline polymer poly-(3-hexylthiophene-2,5-diyl) (P3HT) and the methano-fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), was discussed.
Journal ArticleDOI
Beyond Ternary OPV: High-Throughput Experimentation and Self-Driving Laboratories Optimize Multicomponent Systems.
Stefan Langner,Florian Häse,José Darío Perea,Tobias Stubhan,Jens Hauch,Loïc M. Roch,Thomas Heumueller,Alán Aspuru-Guzik,Christoph J. Brabec,Christoph J. Brabec +9 more
TL;DR: The development of high-throughput and autonomous experimentation methods for the effective optimization of multicomponent polymer blends for OPVs and a method for automated film formation enabling the fabrication of up to 6048 films per day is introduced.
Journal ArticleDOI
P3HT: non-fullerene acceptor based large area, semi-transparent PV modules with power conversion efficiencies of 5%, processed by industrially scalable methods
S. Strohm,Florian Machui,Stefan Langner,Peter Kubis,Nicola Gasparini,Nicola Gasparini,Michael Salvador,Michael Salvador,Iain McCulloch,Iain McCulloch,H.-J. Egelhaaf,Christoph J. Brabec +11 more
TL;DR: In this article, the transfer from poly-3hexylthiophene (P3HT) based fullerene free organic photovoltaic (OPV) lab cells with IDTBR (rhodanine-benzothiadiazole-coupled indacenodithiophene) as acceptor material to fully solution processed roll-to-roll (R2R) compatible modules is reported.
