Advanced Photonics Research, Volume 7, Issue 6, June 2026.A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...

Advanced Science, Volume 13, Issue 31, 4 June 2026.Operando real‐time current density–voltage absorption spectroscopy visualizes spatial phase evolution in mixed‐halide perovskites from device to module scale. Phase instability preferentially initiates in regions with insufficient carrier extraction, revealing electrical boundary conditions as governing factors.

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 643-652, June 2026.This study investigates the UV‐induced degradation of silicon heterojunction cell precursors by isolating the impact of subcell layers under controlled UVA and UVB irradiation. Front hydrogenated amorphous silicon (i/n)a‐Si:H selective layers are identified as key degradation sites, leading to significant losses in minority carrier lifetime and iVoc ( >

Liquid PV Module Encapsulation to Enable Circular Design
Progress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 667-678, June 2026.This study demonstrates a novel liquid encapsulation technology to enable circularity in c‐Si photovoltaic modules. The optical properties and power conversion efficiency of liquid encapsulation is similar to EVA encapsulation and better than air encapsulation.
