Dye-sensitized solar cells (DSCs)as photovoltaics have been subject of intensive research in the last two decades owing to their outstanding features relative thermal stability, low cost, optical tunability, ability operate under conditions poor lighting, and environment friendliness as such, they offer a promising substitute for conventional monocrystalline silicon cells. Their output efficien...

Abstract How to improve the capacity of light‐harvesting is still an important point and essential strategy for assembling high‐efficiency quantum dot–sensitized solar cells (QDSCs). A believable approach implant new light absorption materials into QDSCs stimulate charge transfer. Herein, few‐layer black phosphorus dots (BPQDs) are synthesized by electrochemical intercalation technology using b...

The water splitting properties of InGaN photoanodes equipped with ZnO nanowires were examined in this study. Over the solar spectrum range, the absorbance exhibited a remarkable increase due to the enhanced light absorption caused by the ZnO nanowires. By varying the ZnO nanowires length, the photo-to-current density of photoanodes was increased from 0.017 to 0.205 mA/cm2 at 1.23 V versus rever...

Nanostructured carbon-doped TiO2 (C-TiO2) thin film was prepared by pulsed laser deposition (PLD) on ITO substrate. Results of X-ray diffraction (XRD) analysis of the thin film showed that the crystal structure of the C-TiO2 was a hybrid of rutile and anatase. Data of X-ray photoelectron spectroscopic (XPS) analysis confirmed the successful incorporation of carbon into TiO2 molecules, which for...

The reduction of CO2 to renewable fuels must be coupled a sustainable oxidation process devise viable device that produces solar fuels. In photoelectrochemical cells, water O2 is the predominant reaction and typically requires pair light absorbers or an applied bias voltage when reduction. Here, we report bias-free for simultaneous formate alcohol aldehyde in aqueous conditions. photoanode cons...

Renewable generation of fuels using solar energy is a promising technology whose deployment hinges on the discovery materials with combination durability and solar-to-chemical conversion efficiency that has yet to be demonstrated. Stable operation photoanodes been demonstrated wide-gap semiconductors, as well protected visible gap semiconductors. Visible photoresponse from electrochemically sta...

Anodic TiO2 nanotube (NT) array is promising for the flexible and efficient photoanode in photoelectrochemical water splitting (PECWS) cell. However, photocurrent response of pristine anodic NT literature has a ca 50 times difference, viz. from 0.05 to 1 mA/cm2. Improvement base achieving high anode. Here, we examine size effect different scale on PECWS performance with manipulating macro Ti fo...

Ammonia, produced by human and animal activities, contributes to water soil pollution because it is toxic for aquatic flora fauna, responsible eutrophication. In this work, the photoelectrocatalytic (PEC) oxidation of ammonia investigated employing a stainless-steel PEC reactor, consisting central UV Hg-vapor lamp surrounded metallic Ti mesh coated with photoactive TiO2 film, directly grown Pla...
