I am currently interested in understanding the science that underpins the process of charge carrier extraction at electrode-semiconductor (organic and perovskite) interfaces; development of novel window electrodes for photovoltaics that offer enhanced functionality as compared to conventional metal grid electrodes and transparent conducting oxides; and development of lead-free perovskites and new organic semiconductors for photovoltaic applications.
- Transparent electrodes: Developing scalable, low cost chemical approaches to fabricating nano-structured copper and silver electrodes by micro-contact printing.
- Tin perovskite solar cells: Development of hybrid metal nanoparticle thin films that facilitate efficient extraction of photo-generated charge carriers and also stabilise the perovskite-electrode interface towards oxidation by water and oxygen (which inevitably ingress into the device even with encapsulation!)
- Organic solar cells: Development of air-stable, low work function electrodes for organic solar cells - a path to improving the long term stability of this emerging class of flexible thin film solar cells.
