Perovskites in the news

24 November 2021

This week's Independent newpaper has an article on Perovskite solar cells that describes how chemical disorder can play a key role in device efficiency. Understanding the principles will also help to design Light Emitting Diodes and detectors made with the same materials.

Design rules may help to achieve more than 20% efficiency in organic solar cells

12 October 2021

Coworkers from around the world suggest that new design rules can help control non-radiative pathways for energy loss in organic semiconductor photovoltaic cells. Understanding triplet formation and donor-acceptor hybridisation of orbital wavefunctions is key to achieving devices that approach the theoretical maximum.

Interferometric scattering microscopy (iSCAT) is used to look at transport processes inside batteries, in a collaboration between the Chemistry and Physics Departments. It will help us to explore the fundamental limits in charge and discharge rates in working batteries.

Manganese-doping of perovskite nanocrystals increases their luminescence yields due to an unexpected enhancement of radiative recombination rates. The results demonstrate how transition-metal doping provides precise control of electronic structure and exciton dynamics in metal-halide perovskite nanocrystals and it opens a...

The OE Group is currently 'working from home' in the current Coronavirus situation. This means that telephone calls direct to the Department are unlikely to be answered. However, most people are available on email, though response times might be a little slower than normal...

First Year Students present their reports - July 2019

25 July 2019

Most of the OE and ME First Year PhD students have given presentations this week on their work so far. For many of them, it is the first opportunity to give a talk to the group, and they welcome feedback from colleagues. There were quite a few 'hot topics' - and it was good to be in an air conditioned room, on the hottest...

Winterschool 2019

9 April 2019

The Optoelectronics and Microelectronics groups' 'Winterschool 2019' was a chance at the end of March to compare the energy landscape of novel materials with the ups and downs of Austrian slopes! Evening seminars covered topics such as carrier mobility, DNA structures and Quantum Dots, with fluorescent emission and light...
