Dr. David Fenning is a professor of chemical and nano engineering at UCSD's Jacobs School of Engineering and is serving as our host faculty member for this year's Kyoto Prize Advanced Technology Laureate, Dr. Tsutomu Miyasaka.
From Dr. Fenning’s recent presentation at the Kyoto Prize Symposium Kick-off:
"I want to highlight Prof. Miyasaka's critical contributions to discovering perovskite solar cells and their application space in op electronics. Because of perovskite’s unique properties, we can make devices that already rival the best silicon devices ever made. Silicon PV has been around for almost 75 years. What’s more is that if we put perovskites on top of a silicon cell and join them together in tandem, silicon is better at absorbing infrared light than perovskites. So the perovskites can convert visible light and the silicon cell, infrared, and we can achieve efficiencies already today that are above the thermodynamic limit of what any silicon cell can do. This is the future of solar with the potential to increase energy yield – the power you get out by about 50% relative to what’s out there today.
This has launched a huge effort to commercialize these not just for terrestrial PV but for Space… you will probably see this in many different facet of your life moving forward. So the hope is that perovskite with their relatively earth abundant materials, their low cost manufacturing and their defect tolerance, can really usher in a new era of photovoltaics making it not just more efficient but more equitable and ubiquitous around the world. Prof. Miyasaka is still at the forefront of this field and has been leading the way thinking about safer compositions and lead management – how we can create a more circular perovskite manufacturing environment.
I feel very fortunate to have known Tom for some years… I had a few papers when I first met Tom trying to establish myself as a researcher. He was exceptionally giving of his time and his comments, helped to encourage me to participate in this field as an excited member to see where this can all go rather than discouraging me. Now I’m the national co-director of a perovskite PV center. There’s two in the U.S. We’re working with five or six industrial partners – some of the best institutions and scientists around the country. There’s a lot of effort behind this today and I’m honored to be able to share a little bit of Prof. Miyasaka's story and the story of perovskite cells with you today."
We are extremely excited to recognize Dr. Tsutomu Miyasaka as one of our 2026 Kyoto Prize Laureates!
