Modified Chemical Bath Deposition of Tin Oxide for All‐Scalable Perovskite Solar Modules

open access: yesAdvanced Optical Materials, EarlyView.
A stable and scalable chemical bath deposition method for SnOx electron transport layer is developed using PbCl2 to control hydroxide levels. The resulting films enable smooth morphology and excellent optoelectronic properties. Perovskite solar cells fabricated on these T‐SnOx layers achieve 24.5% efficiency and 1000 h operational stability.

Permittering og sykefravær

open access: yes, 2004
Målet med denne rapporten var å finne ut om det er noen samvariasjon mellom sykefravær og permittering. Bakgrunnen er at lønnstakere har et ikke ubetydelig inntektsbortfall ved en permittering, noe som gir et økonomisk incitament til å bli sykemeldt i stedet.

Resonance Energy Transfer and Purcell Effect in a Cu2O/Au Hybrid Optical Antenna

open access: yesAdvanced Photonics Research, EarlyView.
A Cu2O nanosphere mediates efficient (e.g., 70%) resonance energy transfer (RET) to a gold substrate. The RET damping constant derived from single‐particle scattering, ΓRET$\left(\Gamma\right)_{R E T}$, identifies interband transitions in Au. RET also occurs from an excited electron‐hole pair in Au to the Cu2O/Au hybrid resonator mode, followed by ...

Terahertz Spoof Surface Plasmon Polariton Structure for High‐Precision Gas Sensor Technology

open access: yesAdvanced Photonics Research, EarlyView.
This study presents a high‐sensitivity THz sensor based on spoof surface plasmon polaritons, optimized for gas sensing. The multilayer structure enables placement of the sample material in the densest region of the plasmonic surface waves, enhancing interaction with THz waves and significantly improving sensitivity to small refractive index variations ...

Micromachined Double‐Membrane Mechanically Tunable Metamaterial for Thermal Infrared Filtering

open access: yesAdvanced Photonics Research, Volume 6, Issue 5, May 2025.
Herein, a mechanically tunable double‐layer plasmonic metamaterial leveraging the extraordinary optical transmission effect observed in subwavelength arrays of openings within thin metal layers is presented. The concept is experimentally validated by integrating the proposed metamaterial structure into an electrostatic parallel‐plate actuator to create
