Investigation of CaZrO3−xSx oxysulfide perovskite thin films grown by pulsed laser deposition

JPhys Energy
We aim to identify alternative perovskite candidates for optoelectronic and photovoltaic applications that would combine several key requirements, such as stability, low toxicity, scalability, abundance, and efficacy.

Water‐Coupled Interfacial Modulation Enhances Photovoltaic and Pyroelectric Responses in Transparent Self‐Powered ZnO/NiO Photodetectors

Advanced Science, EarlyView.
Direct water contact enhances the performance of a transparent self‐powered FTO/ZnO/NiO/AgNW/ZnO UV photodetector. Reduced surface reflection improves optical transmission, while an electric double layer at the ZnO/water interface modulates interfacial electrostatics and promotes charge separation.

Low‐Dimensional Metal Halide‐Organic Interdigitated p/n Heterojunction Solar Cells Enabled by Thiomorpholine Hydroiodide Additive

Advanced Electronic Materials, EarlyView.
Thiomorpholine hydroiodide has been developed for regulating crystallization kinetics and passivating defects of two‐dimensional metal halides, enabling the low‐dimensional metal halide‐organic interdigitated p/n heterojunction solar cells to exhibit an efficiency of 24.27% with excellent stability. ABSTRACT Low‐dimensional metal halides are attractive

MXene‐Derived Highly Oriented TiN Enables Ta3N5 Photoanodes for Transmission‐Mode Bias‐Free Solar Water Splitting

Advanced Energy Materials, EarlyView.
This work reports 2D MXene‐derived TiN thin films with (111)‐preferred orientation for transparent Ta3N5 photoanodes, demonstrating effective electron transfer behavior. All‐nitride electron‐collection architecture based on MXene‐derived TiN and n‐GaN resolves a long‐standing materials bottleneck between photocarrier transport and light transmission in

Counter‐Halide‐Directed Ion‐Pair Passivation Enables High‐Performance Wide‐Bandgap Perovskites for Perovskite/Cu(In,Ga)Se2 Tandem Solar Cells

Advanced Energy Materials, EarlyView.
Counter‐halide engineering of fluorobenzylammonium surface passivators reveals bromide as the optimal partner for wide‐bandgap perovskites. FBz–Br effectively stabilizes halide‐vacancy‐related defects and undercoordinated Pb sites, suppresses non‐radiative recombination, and enhances surface hydrophobicity and thermal stability.
