This month, our guest is Stuart Macpherson, Post-doctoral researcher in experimental opto-electronics in the Stranks Lab at the Department of Physics. Stuart’s research focuses on understanding the physics of solar photovoltaics based on perovskite compound, one of the fastest advancing solar technologies of today.

Stuart is also the founder of Sustain/Ed, a non-profit organisation that aims to provide sustainability resources to young students. One of their activities is the energy mapping challenge, aimed at primary school students(9-11 year olds). Through hands-on measurements and data logging, students increase their awareness about climate change and learn how to critically approach scientific problems and apply the knowledge gained to solve real world problems. The project has already been piloted at 6 schools across the country, and is now scaling up further.

Another activity that he has launched with Sustain/Ed is the Sustain/Ed learning module, an educational package which augments the KS2 curriculum in the UK by offering activities which reinforce awareness of sustainability and climate action while maintaining core learning outcomes.

For his projects with Sustain/Ed, in 2021 Stuart was recognised with the Vice Chancellor’s Social Impact Award. But how did his journey in sustainability start? And how does it relate to the technologies he has been developing? We will ask him this and more in our interview. Stay with us…

Please help us get better by taking our quick survey! Your feedback will help us understand how we can improve in the future. Thank you for your time.

[14:25] – Reason behind the PhD decision

[17:40] – Interesting PhD hiring process at Cambridge

[19:56] – Research at Cambridge is on compounds called perovskites that are useful in solar panels

[22:30] – Defects and problems associated with perovskite

[24:43] – In the news this month: Existing copper network cables of UK can support faster internet speeds only to a limit. Researchers say that additional investment is urgently needed if the government is serious about its commitment to making high-speed internet available to all.
