Three‐dimensional Antimony Sulfide Based Flat Optics
Advanced Functional Materials, Volume 36, Issue 32, 20 April 2026.This work presents the development of a grayscale electron beam lithography (g‐EBL) method for fabricating antimony trisulfide (Sb2S3) nanostructures with customizable 3D profiles. The refractive index of g‐EBL patterned Sb2S3 is determined based on the synergy of genetic algorithm and transfer matrix method.

Fresnel Lens Characterization for Solar Concentration Efficiency [PDF]
, 2018 Due to the inexpensive and light weight nature of Fresnel lenses, they are key components in many solar energy concentration systems. Thus, the ability to effectively characterize Fresnel lenses over large areas is essential to verifying their system ...

Advanced Functional Materials, Volume 36, Issue 28, 7 April 2026.This study presents a dynamic interaction between liquid resins and photopolymerized structures enabled by an in situ light‐writing setup. By controlling a three‐phase interface through localized photopolymerization, which provides physical confinement for the remaining uncured resin regions, the approach establishes a programmable pathway that ...

International Journal of Photoenergy, 2018 At present, the Fresnel lens are commonly used as the condenser in high-concentrating photovoltaic (HCPV) modules. It is ideally believed that the output power of a III–V triple-junction solar cell which is placed on the focal plane of a Fresnel lens is ...

Advanced Functional Materials, Volume 36, Issue 32, 20 April 2026.Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...
