Revealing Fundamentals of Charge Extraction in Photovoltaic Devices Through Potentiostatic Photoluminescence Imaging
Lukas Wagner, Patrick Schygulla, Jan Philipp Herterich +10
The photocurrent density-voltage (J(V)) curve is the fundamental characteristic to assess opto-electronic devices, in particular solar cells. However, it only yields information on…
Photo de-mixing in Dion-Jacobson two-dimensional mixed halide perovskites
Ya-Ru Wang, Alessandro Senocrate, Marko Mladenović +7
Two-dimensional (2D) halide perovskites feature a versatile structure, which not only enables the fine-tuning of their optoelectronic properties but also makes them appealing as mo…
Inter-Domain Charge Transfer as a Rationale for Superior Photovoltaic Performances of Mixed Halide Lead Perovskites
Marine E. F. Bouduban, Fabrizio Giordano, Arnulf Rosspeintner +4
Organic-inorganic lead halide perovskites containing a mixture of iodide and bromide anions consistently perform better in donor-acceptor heterojunction solar cells than the standa…
Low-temperature Fabrication of Highly-Efficient, Optically-Transparent (FTO-free) Graphene Cathode for Co-Mediated Dye-Sensitized Solar Cells with Acetonitrile-free Electrolyte Solution
Ladislav Kavan, Paul Liska, Shaik M. Zakeeruddin +1
Propionitrile electrolyte solutions mixed with sulfolane or with 1-ethyl 3-methyl imidazolium tetracyanoborate (ionic liquid) are optimized for Co(bpy)3+/Co(bpy)2+-mediated DSCs wo…
Novel Highly Active Pt/Graphene Catalyst for Cathodes of Cu(II/I)-Mediated Dye-Sensitized Solar Cells
Ladislav Kavan, Hana Krysova, Pavel Janda +6
Novel highly active, optically-transparent electrode catalyst containing Pt, PtOx, graphene oxide and stacked graphene platelet nanofibers is developed for a cathode of Cu(II/I)-me…
Electrochemical Properties of Cu(II/I)-Based Redox Mediators for Dye-Sensitized Solar Cells
Ladislav Kavan, Yasemin Saygili, Marina Freitag +3
Three Cu(II/I)-phenanthroline and Cu(II/I)-bipyridine redox mediators are studied on various electrodes and in variety of electrolyte solutions using cyclic voltammetry and impedan…
