Rapid Cooling After Device Annealing Suppresses Interface Losses in Cu2ZnSnS4 Solar Cells Enabling High Efficiency and Stability

open access: yesAdvanced Science, EarlyView.
Rapid cooling after device annealing regulates the CdS/CZTS heterojunction and Mo/CZTS back contact, suppressing interfacial recombination and modifying the interfacial MoS2 layer, thereby enabling a 15.9% indoor PCE in pure‐sulfide CZTS solar cells.

Circadian‐Inspired Hydrogel Moisture Electricity Generation

open access: yesAdvanced Science, EarlyView.
A circadian‐inspired hydrogel moisture‐electric generator enables sustainable electricity generation by autonomously current direction switching between daytime and nighttime. This reversible output is accompanied by inversion of the internal water gradient, which effectively reduce hydrogel fatigue and offers a new strategy for harvesting diurnal ...

Indoor Position Systems

open access: yes, 2007
I dagens samfunn møter en rekke mennesker utfordringer som vi fleste andre ikke tenker over. Slik samfunnet er i dag er fremkommeligheten til mennesker med permanent eller midlertidig nedsatt funksjonsdyktighet vanskelig mange steder. Begrepet universell utforming omhandler forming av omgivelser og infrastruktur på en slik måte at de kan brukes av alle

Synergistic Effects in Multistate Black Electro‐Thermochromic Smart Windows for Energy‐Efficient Modulation of Solar Heating

open access: yesAdvanced Science, EarlyView.
Hybrid electro‐thermochromic smart windows are developed for dynamic climate control by integrating a redox‐matched black electrochromic gel with a paraffin‐based thermochromic film. This synergistic combination enables multimodal solar modulation, where photothermal heating from the electrochromic layer triggers thermochromic activation at lower ...
