A Numerical Strategy for Achieving Efficiency Exceeding 32% with a Novel Lead‐Free Dual‐Absorber Solar Cell Using Ca3SbI3 and Sr3SbI3 Perovskites

open access: yesAdvanced Photonics Research, EarlyView.
This study develops a highly efficient, lead‐free perovskite solar cell featuring a dual‐absorber system composed of Ca3SbI3 and Sr3SbI3, with SnS2 as the electron transport layer and Spiro‐OMeTAD as the hole transport layer. The proposed double perovskite structure exhibits outstanding power conversion efficiency of 32.74% with a JSC of 34.17 mA cm−2,

Downshifting Layer of Europium‐Doped NaGdF4: From the Optimization of the Sol–Gel Process to the Luminescent Properties

open access: yesAdvanced Photonics Research, EarlyView.
The present approach proposes a high yield production method, using an inexpensive equipment, for the fabrication of lanthanide‐doped ternary fluoride films having high crystallinity and a very homogeneous surface. This efficient sol–gel/spin‐coating approach produces, selectively and reproducibly, the hexagonal undoped and Eu‐doped NaGdF4 films.

High‐Detectivity GeSn Mid‐Infrared Photodetectors for Sensitive Infrared Spectroscopy

open access: yesAdvanced Photonics Research, EarlyView.
This work introduces a complementary metal‐oxide‐semiconductor (CMOS)‐compatible, high‐detectivity mid‐infrared GeSn photodetector monolithically integrated on a silicon platform. Enabled by an innovative composition‐gradient GeSn buffer, the high‐quality, thick GeSn active layer delivers exceptional responsivity and detectivity across the mid‐infrared

Diffractive Synthesis of Multipole Interference States Using Low‐Index Mesoscale Dielectric Structures

open access: yesAdvanced Photonics Research, EarlyView.
Multipole interference (MPI) plays pivotal roles in electromagnetics. In optics, it has been realized typically with the Mie resonance in high‐index, deep‐subwavelength‐scale dielectric resonators. A new, diffraction‐based MPI scheme is proposed and demonstrated with low‐index, mesoscale dielectric structures.
