Operando Charge Carrier Dynamics by Intensity-Modulated Photoluminescence: From Perovskite Thin Films to Solar Cells
Constantin Bach, Dong Won Kim, Yitian Du +2
The charge-carrier lifetime in halide perovskites often varies by orders of magnitude with the injection level, complicating the analysis of conventional time-resolved photolumines…
Mobility-lifetime relation links photodegradation in spin-coated and gravure-printed organic solar cells
Maria Saladina, Paul Weitz, David Holzner +24
The degradation mechanisms of organic solar cells (OSCs) have been studied primarily in spin-coated, laboratory-scale devices, whereas scalable processing modifies the device archi…
Open-Circuit Voltage Limitation by Surface Recombination in Perovskite Solar Cells
Sebastian Reichert, Katelyn Goetz, Christopher Wöpke +2
Fundamental electronic processes such as charge-carrier transport and recombination play a critical role in determining the efficiency of hybrid perovskite solar cells. The presenc…
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…
A facile synthesis method and electrochemical studies of hierarchical structured MoS2/C-nanocomposite
Zhenyou Li, Alexander Ottmann, Elisa Thauer +9
A uniformly coated MoS2/Carbon-nanocomposite with three-dimensional hierarchical architecture based on carbonized bacterial cellulose (CBC) nanofibers is synthesized by a facile on…
Preparation of hierarchical C@MoS2@C sandwiched hollow spheres for Lithium ion batteries
Zhenyou Li, Alexander Ottmann, Ting Zhang +5
Hierarchical C@MoS2@C hollow spheres with the active MoS2 nanosheets being sandwiched by carbon layers have been produced by means of a modified template method. The process applie…
