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…

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…
Evolution of an oxygen NEXAFS transition in the upper Hubbard band in α-Fe2O3 upon electrochemical oxidation
Debajeet K. Bora, Artur Braun, Selma Erat +6
Electrochemical oxidation of hematite (α-Fe2O3) nano-particulate films at 600 mV vs. Ag+/AgCl reference in KOH electrolyte forms a species at the hematite surface which causes a ne…
