Energy Level Alignment in Ternary Organic Solar Cells
Vincent Lami, Yvonne J. Hofstetter, Julian F. Butscher +1
Ternary organic solar cells (TOSC) are currently under intensive investigation, recently reaching a record efficiency of 17.1%. The origin of the device open-circuit voltage (VOC),…
Dipolar Hole-Blocking Layers for Inverted Perovskite Solar Cells: Effects of Aggregation and Electron Transport Levels
Julian F. Butscher, Qing Sun, Yufeng Wu +7
Herein, we report on the synthesis and investigation of two triazino-isoquinoline tetrafluoroborate electrolytes as hole-blocking layers in methylammonium triiodide perovskite phot…
Enhancing the Open-Circuit Voltage of Perovskite Solar Cells by Embedding Molecular Dipoles within their Hole-Blocking Layer
Julian F. Butscher, Sebastian Intorp, Joshua Kress +7
Engineering the energetics of perovskite photovoltaic devices through the deliberate introduction of dipoles to control the built-in potential of the devices offers the opportunity…
Energy Transfer to a Stable Donor Suppresses Degradation in Organic Solar Cells
Andreas Weu, Rhea Kumar, Julian F. Butscher +4
Despite many advances towards improving the stability of organic photovoltaic devices, environmental degradation under ambient conditions remains a challenging obstacle for future…
High-frequency EPR study on CuCu- and CoCo-metallacrown complexes
C. Koo, J. Park, J. Butscher +2
High-frequency/high-field electron paramagnetic resonance studies on two homo-nuclear 12-MC-4 metallacrown complexes CuCu and CoCo are presented. For CuCu, our data imp…
