EPFL unveils perovskite-silicon tandem solar cell with certified efficiency of 30.9%

The tandem solar cell is based on a perovskite top cell treated with an additive known as 2,3,4,5,6-pentafluorobenzylphosphonic acid (pFBPA), which reportedly improves its power conversion efficiency and fill factor. The tandem device also integrates a bottom heterojunction silicon cell made with a 190-μm-thick, 2 Ω.cm, n-type, float-zone, shiny-etched monocrystalline wafer.

Techno-economic feasibility of hydrogen storage in hydro-dominated countries

Scientists have investigated different techno-economic scenarios for using hydrogen storage in combination with hydropower and pumped hydro storage in Switzerland. They have found that hydrogen storage plays no major role under most conditions.

EPFL unveils perovskite solar module with record-breaking efficiency of 23.3%

The solar modules are based on the record-breaking 25.32%-efficient 2D/3D perovskite solar cells that the Ecole Polytechnique Fédérale de Lausanne unveiled in July 2023. The panel has an aperture area of 27.22 cm2, and were encapsulated by glass-glass encapsulation technology combined with an edge seal of the module under UV light illumination.
