Accelerated hot-carrier cooling in MAPbI3 perovskite by pressure-induced lattice compression
Loreta A. Muscarella, Eline M. Hutter, Jarvist M. Frost +4
Hot-carrier cooling (HCC) in metal halide perovskites in the high-density regime is significantly slower compared to conventional semiconductors. This effect is commonly attributed…
Lattice compression increases the activation barrier for phase segregation in mixed-halide perovskites
Loreta A. Muscarella, Eline M. Hutter, Francesca Wittmann +7
The bandgap tunability of mixed-halide perovskites makes them promising candidates for light emitting diodes and tandem solar cells. However, illuminating mixed-halide perovskites…
Thermodynamic stabilization of mixed-halide perovskites against phase segregation
Eline M. Hutter, Loreta A. Muscarella, Francesca Wittmann +7
Mixing iodide and bromide in halide perovskite semiconductors is an effective strategy to tune their bandgap, therefore mixed-halide perovskites hold great promise for color-tunabl…
Mode-selective vibrational control of charge transport in -conjugated molecular materials
Artem A. Bakulin, Robert Lovrinčić, Yu Xi +8
The soft character of organic materials leads to strong coupling between molecular nuclear and electronic dynamics. This coupling opens the way to control charge transport in organ…
Charge-Transfer State Dynamics Following Hole and Electron Transfer in Organic Photovoltaic Devices
Artem A. Bakulin, Stoichko D. Dimitrov, Akshay Rao +7
The formation of bound electron-hole pairs, also called charge-transfer (CT) states, in organic-based photovoltaic devices is one of the dominant loss mechanisms hindering performa…
Charge Trapping Dynamics in PbS Colloidal Quantum Dot Photovoltaic Devices
Artem A. Bakulin, Stefanie Neutzner, Huib J. Bakker +3
The efficiency of solution-processed colloidal quantum dot (QD) based solar cells is limited by poor charge transport in the active layer of the device, which originates from multi…
Femtosecond study of the effects of ions on the reorientation dynamics of water
Sietse T. van der Post, Stefan Scheidelaar, Huib J. Bakker
We study the effects of ions on the reorientation dynamics of liquid water with polarization-resolved femtosecond mid-infared spectroscopy. We probe the anisotropy of the excitatio…
Observation of a stronger-than-adiabatic change of light trapped in an ultrafast switched GaAs-AlAs microcavity
Philip J. Harding, Huib J. Bakker, Alex Hartsuiker +4
We study the time-resolved reflectivity spectrum of a switched planar GaAs-AlAs microcavity. Between 5 and 40 ps after the switching (pump) pulse we observe a strong excess probe r…
