Influence of Dye Adsorbtion Time on TiO2 Dye-Sensitized Solar Cell with Krokot Extract (Portulaca Oleracea. L) as A Natural Sensitizer [PDF]

open access: yesJournal of Pure and Applied Chemistry Research, 2015
Dye sensitized solar cells (DSSC) photoelectrodes were fabricated using titanium oxide (TiO2) and sensitized with the krokot extract dye. This study investigated the effect of dye adsorption time to an efficiency of the solar cells. The fabrication cells

Tuning the Photochemistry of Entatic State Model Systems

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.
We present the photochemistry of the entatic state model [Cu(DMEGqu)2]+/2+, a copper guanidino‐quinoline complex pair. By transient IR and UV/Vis spectroscopy, we obtained the lifetimes of the different excited states. We show that the structural effect of the guanidine tunes the photochemistry of this entatic state model.

A Study on Enhancing Stability and Conductivity of ZnO Through Controlled Doping

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 6, June 2026.
First principles modelling reveals vanadium and indium as complementary tuning knobs in cubic ZnO, enabling controlled changes in optical absorption, dielectric screening, and frequency‐dependent conductivity. Moderate doping maximizes optoelectronic gain, while higher loading can trigger mechanical softening.

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

open access: yesAggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Ion‐Pairing and Counterion Effects in Contemporary Photochemistry

open access: yesAngewandte Chemie Novit, Volume 2, Issue 2, June 2026.
Ion‐pairing and counterion effects have emerged as fundamental yet underexplored determinants of photochemical behavior. Far from inert, counterions, and Coulombic interactions modulate excited‐state dynamics, quenching efficiencies, emission, and catalytic pathways.

Outdoor Measurements of Perovskite Modules

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 679-692, June 2026.
Performance of a single junction perovskite module (total area of 0.7164 m2) during 1 year of outdoor monitoring. ABSTRACT For the PSC PV to be a competing technology with silicon and thin film PV technologies more data from field installations need to be studied and examined.

Influence of TiO2 Film Thickness on the Electrochemical Behaviour of Dye-Sensitized Solar Cells

open access: yesInternational Journal of Electrochemical Science, 2011
A commercial TiO2 powder was deposited on F-doped SnO2 (FTO) glass substrates by a spray coating technique with different thicknesses (6, 10 and 14 µm) to be used as photo-anode in dye-sensitized solar cells (DSSCs). N3 dye was adsorbed on each TiO2 film
