Infrared thermography for dynamic thermal transmittance determination

open access: yes, 2019
The aim of this paper is to show a new possibility for in situ U-value determination using infrared thermography (IRT) method and its comparison with heat flux method (HFM). It also gives procedure for conducting the experiment and for the analysis of measured data.

Transmittance scaling for reducing power dissipation of a backlit TFTLCD

open access: yes, 2004
This chapter presents transmittance scaling; a technique aimed at conserving power in a transmissive TFT-LCD with a cold cathode fluorescent lamp (CCFL) backlight by reducing the backlight illumination while compensating for the luminance loss. This goal

Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows

open access: yesAdvanced Science, EarlyView.
We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

Quenching Photo‐Induced Free Radicals Endows Superomniphobic Atmospheric Water Harvesting Hydrogels With UV Resistance for Durable Bifacial Photovoltaic Cooling

open access: yesAdvanced Science, EarlyView.
A hygroscopic hydrogel layer functionalized with fullerene C60 tackles heat and dust challenges in bifacial photovoltaics (PV) panels. It resists soiling and photo‐aging, maintains high transparency, absorbs water vapor from the air during the night, and delivers strong evaporative cooling power during daytime, significantly lowering PV panel ...

Hybrid Semi‐Transparent Perovskite‐Photovoltaics and Concentrated Solar‐Thermal Harvesting Collectors

open access: yesAdvanced Science, EarlyView.
A hybrid semi‐transparent perovskite‐photovoltaic and concentrating solar‐thermal collector is developed to spectrally split sunlight for simultaneous electricity and heat generation. The design achieves thermal decoupling between the photovoltaic and thermal components, offering a promising route for efficient co‐harvesting of solar electricity and ...

Water‐Coupled Interfacial Modulation Enhances Photovoltaic and Pyroelectric Responses in Transparent Self‐Powered ZnO/NiO Photodetectors

open access: yesAdvanced Science, EarlyView.
Direct water contact enhances the performance of a transparent self‐powered FTO/ZnO/NiO/AgNW/ZnO UV photodetector. Reduced surface reflection improves optical transmission, while an electric double layer at the ZnO/water interface modulates interfacial electrostatics and promotes charge separation.
