Flexible solar cells with record efficiency of 22.2%

One year after announcing an efficiency record, Empa scientists have achieved a new mark of 22.2% for flexible CIGS solar cell on polymer film. Solar cells of this type are especially suited for applications on buildings, vehicles, satellites, airships, and mobile devices. Empa researchers have – once again – improved the efficiency of CIGS flexible Read more about Flexible solar cells with record efficiency of 22.2%[…]

Solar Cell boost production using heterojunction technology to replace silver with copper

When it comes to generating electricity from renewable energies, photovoltaics are a mainstay. Modern heterojunction solar cells have a particularly low CO2 footprint on account of the low amounts of silicon used to produce them, and when it comes to industrial production, they achieve the highest levels of efficiency. As a result, the chances are high Read more about Solar Cell boost production using heterojunction technology to replace silver with copper[…]
