Keith talks with Peter Bäuerle at the Institute of Organic Chemistry II and Advanced Materials of Ulm University, Germany. Peter is researching the development of organic photovoltaics which can be used as an alternative to the more commonly-used silicon voltaics. Organic solar foils can be more lightweight, flexible, and transparent than silicon solar foils, and may even be used to cover buildings, glass roofs of cars, and windows.
