Progress in Photovoltaics: Research and Applications, EarlyView.Front contact selection governs interfacial stability in CdTe‐based (Cd(Se,Te)) solar cells on ultra‐thin space‐qualified cover glass. Optimized TCO/emitter combinations suppress interdiffusion and deliver up to 16.2% AM0 efficiency with high specific power, demonstrating strong potential for lightweight space photovoltaics.

Progress in Photovoltaics: Research and Applications, EarlyView.Amorphous SnO2 films with low resistivity (~1.2 × 10−3 Ωcm) were realized by low‐temperature magnetron sputtering through control of O2 flow ratio, substrate temperature, and H incorporation. Si heterojunction solar cells incorporating these films achieved a conversion efficiency of 21.1%, approaching that of cells based on MS‐ITO and RPD‐SnO2 ...

Responsive Materials, EarlyView.Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Small, EarlyView.Bacterial viability is determined in a complex environment with a field‐effect biological transistor with a limit of detection of a single bacterium. Living, antibiotic‐treated, thermally denatured, and inhibited E. coli generate distinct electrical signatures, enabling label‐free single‐cell detection and providing new opportunities for rapid ...

Small Methods, EarlyView.This study demonstrates the detection of virus‐sized single polystyrene particles in water by leveraging the ultrahigh‐Q nature of low‐contrast bound states in the continuum (BIC) metasurfaces. The resonance properties of silicon BIC metasurfaces—wavelength, linewidth, and amplitude—all exhibit single‐particle sensitivity, representing a unique sensing
