Nanoscale Rear‐Interface Architecture Enables 36.2 mA cm−2 Photocurrent in Ultrathin and Bifacial ACIGS Solar Cells Through Light Management

Laser &Photonics Reviews, EarlyView.
An array of SiOx nanopillars is developed on ITO transparent rear contacts through nanoimprint lithography to promote light scattering in 500–600 nm bifacial ACIGS solar cells. This architecture increases the short‐circuit current density by 7.8 and 7.6 mA cm−2 under front (up to 36.2 mA cm−2) and rear illumination, respectively, offering a scalable ...

Indium‐Free Silicon Heterojunction Solar Cells: Achieving High Conductivity With Magnetron‐Sputtered SnO2

Progress in Photovoltaics: Research and Applications, EarlyView.
Amorphous SnO2 films with low resistivity (~1.2 × 10−3 Ωcm) were realized by low‐temperature magnetron sputtering through control of O2 flow ratio, substrate temperature, and H incorporation. Si heterojunction solar cells incorporating these films achieved a conversion efficiency of 21.1%, approaching that of cells based on MS‐ITO and RPD‐SnO2 ...

Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

Responsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Visualizing Gradual Aging of Lateral Heterostructured MoS2‐WS2 Under Vacuum Conditions by Hyperspectral Phase Microscopy

Small, EarlyView.
This study visualizes the long‐term aging of lateral MoS2‐WS2 heterostructures stored under low‐vacuum condition using hyperspectral phase microscopy (HPM). While conventional techniques show limited sensitivity to ultrathin and amorphous oxidation products, HPM successfully reveals morphological and optical changes during aging. Optical modeling using

Investigation of Tin Oxide Atomic Layer Deposition on the Performance of Evaporated Perovskite Solar Cells

Small, EarlyView.
Impact of co‐reactants and their doses utilized during the atomic layer deposition of SnOx on perovskite/C60 structures on the performance of p‐i‐n perovskite solar cells. ABSTRACT Although tin oxide (SnOx) layers grown using atomic layer deposition (ALD) are routinely employed in p‐i‐n perovskite solar cells (PSCs), the correlation between ALD process
