First-principles analysis of the interplay between electronic structure and volume change in colquiriite compounds during Li intercalation
A. F. Baumann, D. Mutter, D. F. Urban +1
A main source of capacity fading in lithium-ion batteries is the degradation of the active cathode materials caused by the series of volume changes during charge and discharge cycl…
Weak dispersion of exciton Landé factor with band gap energy in lead halide perovskites: Approximate compensation of the electron and hole dependences
N. E. Kopteva, D. R. Yakovlev, E. Kirstein +11
The photovoltaic and optoelectronic properties of lead halide perovskite semiconductors are controlled by excitons, so that investigation of their fundamental properties is of crit…
The Landé factors of electrons and holes in lead halide perovskites: universal dependence on the band gap
E. Kirstein, D. R. Yakovlev, M. M. Glazov +16
The Landé or -factors of charge carriers are decisive for the spin-dependent phenomena in solids and provide also information about the underlying electronic band structure. We…
Removing Leakage and Surface Recombination in Planar Perovskite Solar Cells
K. Tvingstedt, L. Gil-Escrig, C. Momblona +6
Thin-film solar cells suffer from various types of recombination, of which leakage current usually dominates at lower voltages. Herein, we demonstrate first a three-order reduction…
Persistent photovoltage in methylammonium lead iodide perovskite solar cells
A. Baumann, K. Tvingstedt, M. C. Heiber +4
Open circuit voltage decay measurements are performed on methylammonium lead iodide (CH3NH3PbI3) perovskite solar cells to investigate the charge carrier recombination dynamics. Th…
Nongeminate recombination in neat P3HT and P3HT:PCBM blend films
Julien Gorenflot, Michael C. Heiber, Andreas Baumann +5
The slow decay of charge carriers in polymer-fullerene blends measured in transient studies has raised a number of questions about the mechanisms of nongeminate recombination in th…
