Solar module for east-west installations on flat rooftops
Dutch startup Solarge has developed a 500 W panel that weighs 50% less than conventional glass-backsheet modules. The new product can be fixed to rooftops with roofing anchors, which eliminates the need for ballast, according to the manufacturer.
Swiss scientists achieve 21.4% efficiency for flexible CIGS solar cell
The result was confirmed by Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). The cell was fabricated through a low-temperature co-evaporation method for the growth of the light-absorbing CIGS semiconductor thin film.
