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),…
Sequentially Deposited versus Conventional Nonfullerene Organic Solar Cells: Interfacial Trap States, Vertical Stratification, and Exciton Dissociation
Jiangbin Zhang, Moritz H. Futscher, Vincent Lami +16
Bulk-heterojunction (BHJ) non-fullerene organic solar cells prepared from sequentially deposited donor and acceptor layers (sq-BHJ) have recently been promising to be highly effici…
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…
Ligand Dependent Oxidation Dictates the Performance Evolution of High Efficiency PbS Quantum Dot Solar Cells
David Becker-Koch, Miguel Albaladejo Siguan, Vincent Lami +4
Lead sulfide (PbS) quantum dot (QD) photovoltaics have reached impressive efficiencies of 12%, making them particularly promising for future applications. Like many other types of…
Efficient and Stable PbS Quantum Dot Solar Cells by Triple-Cation Perovskite Passivation
Miguel Albaladejo-Siguan, David Becker-Koch, Alexander D. Taylor +5
Solution-processed quantum dots (QDs) have a high potential for fabricating low cost, flexible and large-scale solar energy harvesting devices. It has recently been demonstrated th…
