Sb<sub>2</sub>S<sub>3</sub> films for efficient Sb<sub>2</sub>S<sub>3</sub>-based solar cells can be obtained through annealing a bilayer of antimony acetate and thiourea films.
Hydrothermal deposition was recently developed to prepare an antimony selenosulfide thin film with large grain size and flat compact surface morphology, leading efficient breakthrough in solar cell applications. However, the of chalcogenide is always based on CdS substrate. The narrow band gap generates parasitic absorption that causes light harvesting loss device. TiO2 a wide allows more harvesting, while its high-quality films has not been realized. Here, we demonstrate Sb2S3 seed layer...

Si-Based microdisks with Ge quantum dots (QDs) have been of great interest due to their potential as the desired light source for monolithic optical-electronic integrated circuits (MOEICs), well in studies cavity electrodynamics (CQED). Here, we report on unique SiGe nanodisk arrays embedded QDs directly realized bulk Si substrates. Their superior optoelectronic properties are demonstrated by remarkably enhanced photoluminescence coupling between QD emissions and modes nanodisk, even though...
Abstract Although lithium–oxygen batteries possess a high theoretical energy density and are considered as promising candidates for next‐generation power systems, the enhancement of safety cycling efficiency lithium anodes while maintaining storage capability remains difficult.

Sources of single photons in pure quantum states are essential to many optics applications. We explore a technique, known as group-velocity matching, that enables the heralded generation through nonlinear optical processes. It reduces or eliminates requirement spectral filtering conventional sources rely on achieve high purity, therefore increasing both heralding efficiency and photon flux. Implementation spontaneous parametric downconversion four-wave mixing is studied we discuss several...
