A new solar module has set a new efficiency standard
A Swiss company has developed technology for significantly increasing the efficiency of solar modules. The first products are anticipated to launch on the market in 2022.7 Mar 2019 Roland Freist
The new approach , developed by Lausanne-based Insolight , concentrates light onto an array of multi-junction photovoltaic cells. The Insolight panel’s protective glass comprises a grid of lenses which concentrate light several hundred times on an array of high-performance solar cells. So that it can follow the sun’s movement, this cell array is mobile and shifts by just a few millimeters each day. The whole system is encased in a slim module, which keeps mechanical parts protected.
Insolight’s concept was tested in a laboratory at the Fraunhofer Institute for Solar Energy Systems ISE in 2016 and subsequently further developed. In November 2018, the Solar Energy Institute of the Technical University of Madrid ( IES-UPM ) validated the Swiss company’s solar modules at a nominal peak efficiency of 29%; standard modules typically show an efficiency of just 17-19%. Insolight is currently working on an industrialization strategy for large-scale production and is in talks with a number of solar manufacturers on licensing its technology.
