Advanced solar technologies
A lot still needs to be done to make the most of the sun as a resource. Solar panel efficiency must continue to increase. And production and purchase costs must be reduced. To achieve this, we work with manufacturers on materials, technologies, and innovations. Examples are silicon PV, thin-film perovskite, and tandems.

Solar technology: opportunities and challenges
TNO is innovating in order to make solar energy affordable and available to all.
Our latest developments
Dutch-German consortium develops simplified tandem solar modules for European market
In cooperation with Dutch and German industrial partners, TNO is advancing a tandem solar module suitable for early market introduction. This application can reach higher efficiencies than those achieved by current silicon-based solar modules, which results in more power per square meter and lower cost per kWh.


Angèle Reinders new director Solliance
Angèle Reinders, professor at Eindhoven University of Technology (TU/e), has been appointed Solliance's new director. Reinders will lead the new broad focus of the Dutch/Flemish/German solar energy partnership.


Four terminal perovskite-silicon PV tandem devices hit 30% efficiency
TNO, TU Eindhoven, imec and TU Delft, partners in Solliance, joined forces to further push the conversion efficiency of tandem solar cells to beyond the limits of today’s commercial photovoltaic (PV) modules.


Putting Europe back in the lead in solar panel production
Most solar panels come from China. Time to bring the solar panel production back to Europe. With smart solutions from TNO.
