Hi, I’m Hsuanyu Wang. I completed my MSci Chemistry Degree at Imperial College London. I have a strong interest in green energy generation. I participated in an Undergraduate Research Opportunity Program in Prof. James Durrant’s group, where I used UV-vis to determine the glass transition temperature of photoresponsive organic materials. For my Master’s project, I worked under the supervision of Dr. Nicola Gasparini on enhancing the photochemical stability of organic photovoltaics through nature-inspired stabilizers.
For my PhD, I will continue my Master’s project, researching under the supervision of Dr. Vida Engmann at SDU. My project focuses on investigating the feasibility of incorporating antioxidants into a wider range of novel organic materials to enhance OPV's operational lifetime.

In November 2024, Devina joined Professor Heinz Amenitsch in CERIC-ERIC, Trieste as an MSCA-DN fellow in the OPVStability program. Her project focus is on the effect of environmental conditions on the stability and morphology of absorber layers and interfacial regions.

Manan Mehta

holds a Master of Research degree (2022) in Soft Electronic Materials from Imperial College London. He worked with Dr Piers Barnes on Perovskite based Memristors, Transistors and Memtransistors, and showed that ionic screening is responsible for poor gate modulation in perovskite transistors using simulations and demonstrated the first instance of gate-modulated filamentary resistive switching behaviour in perovskite memristive devices using experimental methods, and subsequently winning the Outstanding Achievement Award for Core Course on the MRes Soft Electronic Materials Course. In February 2024, he started his PhD under the supervision of Mariano Campoy-Quiles co-supervised by Sergi Riera-Lorente within the MSCA-DN programme, OPVStability, which aims to use high-throughput screening of organic materials for screening for power conversion efficiency and stability, evaluation of novel systems and processing parameter space, and study of large datasets that will be employed to feed statistical tools and artificial intelligence models.
