The Use of ZnO Quantum Dots to Improve the Electrical Properties of Silicon Solar Cells.

Silicon-based solar cells dominate the photovoltaic market, with commercial monocrystalline silicon cells reaching efficiencies as high as 27.3% by May 2024. An alternative to monocrystalline silicon solar cells is polycrystalline solar cells.

Tuning the Optical Properties of Electrospun Poly(methyl methacrylate) Nanofibres via Montmorillonite and Magnetite Ratios.

Poly(methyl methacrylate) (PMMA) polymer has unlocked new frontiers in the field of nanotechnology and is suitable for a wide range of applications. However, its optical band gap limits its use in optoelectronics. This study aims to ascertain the influence of varying montmorillonite and magnetite ratios on the optical properties of electrospun PMMA nanofibres produced from solution.

Correction: Photocatalytic membranes based on Cu-NH-MIL-125(Ti) protected by poly(vinylidene fluoride) for high and stable hydrogen production.

Correction for 'Photocatalytic membranes based on Cu-NH-MIL-125(Ti) protected by poly(vinylidene fluoride) for high and stable hydrogen production' by Emilia Gontarek-Castro , 2025, https://doi.org/10.1039/d4mh01397b.

Photocatalytic membranes based on Cu-NH-MIL-125(Ti) protected by poly(vinylidene fluoride) for high and stable hydrogen production.

A porous, photocatalytically active, and water-stable composite membrane has been developed based on Cu-NH-MIL-125(Ti), a titanium-based metal-organic framework (MOF) and PVDF polymeric matrix. To tune the structural and functional properties of the PVDF/MOF composites, the loading degree of the MOF within the polymer was systematically varied. The most effective performance of the composite material was achieved with a 10% wt/wt loading of MOF into the PVDF matrix.

Cu-incorporated NH-MIL-125(Ti): a versatile visible-light-driven platform for enhanced photocatalytic H generation and CO photoconversion.

Here, we present for the first time an efficient platform for simultaneous H generation and CO conversion into HCOOH, utilizing a Cu-incorporated NH-MIL-125(Ti) material with triethanolamine as the sacrificial agent. When subjected to light, Cu-NH-MIL-125(Ti) exhibits a remarkable enhancement in H generation, with a 30-fold increase under UV-Vis light and an 8-fold increase under visible irradiation compared to the pristine MOF. The study on the CO photoreduction ability of Cu-NH-MIL-125(Ti) indicated successful conversion into formic acid yielding 62.
