Victoria’s Perovskite Paper Accepted in JPCL

Victoria’s paper, Investigating the Role of the Organic Cation in Formamidinium Lead Iodide Perovskite using Ultrafast Spectroscopy has just been accepted in the Journal of Physical Chemistry LettersVictoria’s work addresses the controversial topic of long-lived (anti-) ferroelectric domains through organic cation alignment in lead-halide perovskite thin films using two-dimensional infrared spectroscopy. Through anisotropy measurements, Victoria showed that alignment was short-lived and cannot explain the observed low charge-carrier recombination rates. Complimentary time-resolved infrared measurements examined the vibrational dynamics of the cation in the conduction band. These data show an unusual enhancement of the vibrational dipole moment due to nascent proximal charge carriers. The very talented Dr. Devendra Tiwari prepared the thin film samples using a novel preparation method. The studies were performed both at Bristol and the Rutherford Appleton Laboratory. The ASAP version of the paper can be found here and the work is featured on the School of Chemistry’s news website.

Faraday Discussion 2019

A Faraday Discussion focused on exploring ‘Ultrafast Photoinduced Energy and Charge Transfer’ has finally been confirmed for 8-10 April 2019 in Ventura, California. The four main themes of the meeting are: Energy and charge transport in natural photosynthesis, photovoltaics and bio-inspired light harvesting, photo-induced electron transfer, photo-protection/photo-damage in natural systems.

Details of the opening and closing lectures, and invited speakers will be available shortly, and found on the RSC website.
