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…
Improved evaluation of deep-level transient spectroscopy on perovskite solar cells reveals ionic defect distribution
Sebastian Reichert, Jens Flemming, Qingzhi An +3
One of the key challenges for future development of efficient and stable metal halide perovskite solar cells is related to the migration of ions in these materials. Mobile ions hav…
Enhancing the Open-Circuit Voltage of Perovskite Solar Cells by up to 120 mV using π-Extended Phosphoniumfluorene Electrolytes as Hole Blocking Layers
Qingzhi An, Qing Sun, Andreas Weu +7
Four π-extended phosphoniumfluorene electrolytes (π-PFEs) are introduced as hole-blocking layers (HBL) in inverted architecture planar perovskite solar cells (PVSCs) with the struc…
