Dynamic Disorder Dominates Delocalization, Transport, and Recombination in Halide Perovskites

December 13th, 2018|

First illustration of infrared transient absorption measurement using an inspIRe transient absorption spectrometer at excitation conditions many orders of magnitude lower than previously possible. Capability was central to the realization that dynamic disorder leads to order of magnitude longer carrier lifetimes in halide perovskite photovoltaics.

Electron−Phonon Coupling and Resonant Relaxation from 1D and 1P States in PbS Quantum Dots

May 24th, 2018|

First report of formally forbidden 1S-1D excitonic transitions observed in PbS quantum dots using combined spectra from inspIRe and enVISion transient absorption spectrometers. The ability to measure small spectral features of forbidden transitions with high fidelity was central to revealing resonant relaxation pathways that bypass the phonon bottleneck.

Harnessing Molecular Vibrations to Probe Triplet Dynamics during Singlet Fission

November 7th, 2017|

Utilization of molecular vibrations to interrogate the mechanism of triplet exciton formation during singlet fission. Mid-IR transient absorption spectra collected on an inspIRe were used to identify vibrational signatures of triplet electronic states in TIPS-Pentacene that were used to track the singlet fission mechanism on ultrafast timescales.

Molecular Rectification in Conjugated Block Copolymer Photovoltaics

March 21st, 2016|

Demonstration of selective, directional charge transfer in the first efficient fully conjugated block copolymer photovoltaic material. The ability to seamlessly connect ultrafast and nanosecond time scale infrared transient absorption measurements using a prototype of the inspIRe was key to demonstrating the selectivity for charge transfer that underpinned the high performance of the system.
