Design, experimental, and theoretical investigation of the solar concentrating thermal system

Next Energy
Concentrated solar thermal (CSP) systems suffer from low thermal efficiency due to high heat losses, uneven distribution of solar flux on the conventional thermal receiver, and poor absorption of solar radiation.

Spectral Splitting Using Luminescent Solar Concentrator Lightguides

Advanced Optical Materials, EarlyView.
Attaching selective reflectors to the edges of a luminescent solar concentrator containing two different fluorescent dyes makes it possible to parse the incident white light spectrum into two separate edge emission wavelengths. Separation may be enhanced by aligning the dichroic dyes on the lightguide surface.

Post‐Deposition Photonic Curing Treatment for Improved Sb2Se3 Photovoltaic Performance

Advanced Optical Materials, EarlyView.
Millisecond‐scale photonic curing overcomes the open‐circuit voltage deficit in Sb2Se3 solar cells by transforming the rear interface. This ultrafast treatment enhances crystallographic texture and smooths the absorber surface, suppressing interfacial recombination and boosting power conversion efficiency to 8.2%.

Cyclodextrin‐Functionalized Light‐Driven Cu2O Micromotors for Simultaneous Capture and Degradation of Bisphenol A

Advanced Robotics Research, EarlyView.
Fuel‐free Cu2O‐based micromotors functionalized with β‐cyclodextrin actively remove bisphenol A from water under visible light. The cyclodextrin shell captures BPA and enhances micromotor motility, leading to faster degradation and higher overall removal than nonfunctionalized Cu2O and Cu2O@Au.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

Advanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

Advanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen
