To realize the green energy transition, proton exchange membrane (PEM) water electrolyzers have attracted significant interest for green hydrogen production. (1−3) A clear benefit of PEM over other methods like alkaline water electrolysis (AWE) is that PEM systems respond much more quickly to changes in power input, making them ideal for pairing with intermittent renewable energy sources like solar and wind.

Introduction Click to copy section linkSection link copied! Silicon-based field-effect transistors (FETs), the fundamental components of integrated circuits, are approaching their physical limits at physical gate lengths of approximately 10 nm. (1) New materials may be capable of overcoming these constraints, thus enabling the continuation of miniaturizing integrated circuits.

Efficient light management in monolithic perovskite/silicon tandem solar cells is one of the prerequisites for achieving high power conversion efficiencies (PCEs). Textured silicon wafers can be utilized for light management, however, this is typically not compatible with perovskite solution processing. Here, we instead employ a textured light management (LM) foil on the front-side of a tandem solar cell processed on a wafer with a planar front-side and textured back-side.
