International Cooperation
International cooperation continues on two levels, academic and industrial. Research activities involve,
among others, laboratories engaged in nanotechnology in Denmark (University of Arhus), Ireland
(University College Dublin), Scotland (University of Aberdeen) and Algeria (University of Setif). The
laboratory also collaborated with the University of Rome, Tor Vergata, in the organisation of an international
seminar on DSC, held in Ventotene, Italy (Sept.2007). In Asia there are ongoing contacts with
India, China, Japan and Korea.
At the St. Gallen conference already mentioned, G24i PLC, Wales, a license holder of EPFL DSC
patents, presented a recently commissioned production line which entered into service in June 2007.
Significant progress was also reported by Dyesol PLC, Australia, another industrial associate company:
tests of a Dyesol state-of –the-art device established a durability under continuous simuated 1sun
illumination of 14,000 hours, with the test continuing. This represents a major milestone in the
qualification of DSC technology for long-duration operation in outdoor conditions. Scaling for natural
variability of operating conditions, including the day/night cycle and weather effects, this observation
justifies confidence in a 20-year lifetiime for DSC photovoltaic solar electricity generation.
