Charge recombination suppressed CdSeS/CdSe/ZnS QDSSC design

Hacettepe 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.

Low-cost portable dielectric spectrometer based on mini-vector network analyzer and open-ended coaxial probe technology

Nano Research
Laser-based light sources are highly desirable for display applications due to their narrow emission linewidth and exceptional brightness. However, the coherence inherent in lasers often leads to the formation of unwanted speckles, which can ...

Study of Photoconductivity of Thin Films of Cadmium and Selenium Obtained by Chemical Deposition

East European Journal of Physics
In this work, the photoconductivity (PC) spectrum of thin CdSe films was studied. In the course of studies on glass substrates, thin films of cadmium and selenium with a thickness of h = 200 nm and h = 400 nm were selected.

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Effect of ligand exchange on photocurrent enhancement in cadmium selenide (CdSe) quantum dot water splitting cells

Results in Physics, 2018
We report photocurrent enhancement through ligand exchange in cadmium selenide (CdSe) photoelectrochemical (PEC) cells. CdSe quantum dot (QD) layers were used as a light absorption layer in combination with titanium dioxide (TiO2) layers.
