Charge recombination suppressed CdSeS/CdSe/ZnS QDSSC design

open access: yesHacettepe Journal of Biology and Chemistry, 2021
The interest in quantum dot sensitized solar cells (QDSSC), which has theoretically proved to have up to 44% energy conversion efficiency in recent years, is growing rapidly. Although it has theoretically high efficiency value, PCE obtained in studies with QDSSCs is far from these values.

Polarized light emission by deposition of aligned semiconductor nanorods [PDF]

open access: yes, 2014
The ability to control the position and orientation of nanorods in a device is interesting both from a scientific and a technological point of view. Because semiconductor nanorods exhibit anisotropic absorption, and spontaneous and stimulated emission ...

Electrodeposition of Nanoparticles and Continuous Film of CdSe on n-Si (100)

open access: yesNanomaterials, 2019
CdSe electrodeposition on n-Si (100) substrate was investigated in sulfuric acid solution. The behaviour and the deposition of the precursors (Cd and Se) were studied separately at first. Then, we explored both the alternated deposition, one layer by one,

The Electronic Structure of CdSe/CdS Core/Shell Seeded Nanorods: Type-I or Quasi-Type-II? [PDF]

open access: yes, 2013
The electronic structure of CdSe/CdS core/shell seeded nanorods of experimentally relevant size is studied using a combination of molecular dynamics and semiempirical pseudopotential techniques, with the aim to address the transition from type-I to a ...

Exceptional co-catalysts free SrTiO3 perovskite coupled CdSe nanohybrid catalyst by green pulsed laser ablation for electrochemical hydrogen evolution reaction

open access: yesChemical Engineering Journal Advances, 2022
In this study, a facile and green PLAL technique was used to synthesize nanohybrids consisting of SrTiO3/CdSe, as efficient cathode material for electrocatalytic HER in a basic medium. Although pure SrTiO3 perovskite has poor electrocatalytic performance,

CdSe Nanoplatelets: Living Polymers [PDF]

open access: yesAngewandte Chemie International Edition, 2016
AbstractColloidal CdSe nanoplatelets are considered to be excellent candidates for many applications in nanotechnology. One of the current challenges is to self‐assemble these colloidal quantum wells into large ordered structures to control their collective optical properties. We describe a simple and robust procedure to achieve controlled face‐to‐face

Electron and Phonon Confinement and New Surface Phonon Modes in CdSe-CdS Core-Shell Nanocrystals [PDF]

open access: yes, 2004
Optical and vibrational properties of bare and CdS shelled CdSe nanocrystalline particles are investigated. To confirm the formation of such nanocrystals in our samples we estimate their average particle sizes and size distributions using TEM ...

Incorporation of Mn2+ into CdSe quantum dots by chemical bath co-deposition method for photovoltaic enhancement of quantum dot-sensitized solar cells [PDF]

open access: yesRoyal Society Open Science, 2018
A photoelectric conversion efficiency (PCE) of 4.9% was obtained under 100 mW cm−2 illumination by quantum-dot-sensitized solar cells (QDSSCs) using a CdS/Mn : CdSe sensitizer.

Perceived parenting styles, thinking styles, and gender on the career decision self-efficacy of adolescents: how & why?

open access: yesHeliyon, 2021
Career decision self-efficacy (CDSE), i.e., the ability to successfully make important career-related decisions, is influenced by perceived parenting styles, thinking styles, and gender.
