Solar & Storage Live Zurich 2025 reflects growth of Swiss PV sector
At the Solar & Storage Live trade fair, Swiss and European wholesalers were represented with products from manufacturers in Germany, Lithuania, Norway, Switzerland, and, of course, China. Some manufacturers also had their own booths, and there was also a new area for installers.
Meyer Burger gives up on selling itself as a whole, sells U.S. solar production tools
Sales of module and cell production equipment to, respectively, Waaree Solar Americas and Babacomari North Solar further thin chances of any Meyer Burger revival of its domestic production.
SolarStratos reaches 8,224 m height
Swiss pilot Raphaël Domjan flew the SolarStratos solar-powered aircraft to 8,224 meters on Aug. 10, setting a personal record but falling short of the 9,235-meter world mark held by Solar Impulse.
Solar on the tracks
Swiss startup Sun-Ways inaugurated its railway PV project in April in Neuchatel, Switzerland, after more than two years of planning. Joseph Scuderi, founder of Sun-Ways, tells pv magazine that the pilot is attracting international attention.
High-temperature co-annealing step could cut TOPCon cell costs
Researchers at the Ecole Polytechnique Fédérale de Lausanne (EPFL) have proposed combining the two high-temperature steps used in producing tunnel oxide passivated contact (TOPCon) solar cells into a single co-annealing process. Initial results show promising outcomes in boron concentration, passivation quality, and contact resistivity.
Bottom-up cost model for perovskite solar module manufacturing
Scientists in Switzerland have conducted techno-economic analysis of perovskite solar module manufacturing costs in terms of levelized cost of energy and have found that these products could be competitive in the Alpine country provided that they achieve an efficiency of over 24% with a lifespan of 20 years and over 20% with a lifecycle of 30 years.
Swiss researchers seek to simplify TOPCon cell production with single-step annealing process
A Swiss research team has developed a novel single-step annealing process for tunnel oxide passivating contact (TOPCon) solar cells. Demonstrating the approach, the scientists built a proof-of-concept TOPCon device with a 21% efficiency.
New research confirms residential PV tends to increase household power consumption
New Swiss research shows PV-powered homes can increase power consumption by up to 11% compared to non-solar households. This rise is linked to electric vehicle adoption or other high-usage appliances, which the study’s author notes is not inherently negative or wasteful.
Swiss developer breaks ground on 1.6 GWh redox flow storage project
The redox flow project has enormous storage capacity, expected to be finished in mid-2028.
Glass-free, colored PV modules for building rooftop retrofits, façades
Researchers from Swiss and Austrian institutions have demonstrated a novel design for a glass-free, structurally robust silicon PV module. With a weight below 6 kg/m2, the targeted application is older buildings with weak roof structure.
