However, this ligand colloid film has poor conductivity. By introducing the selenium in both the core (cadmium selenide) and shell (zinc selenide) of QDs 4 , Shen was able to stabilize the QD-LEDs ...

Scientists in China built for the first time a four-terminal tandem perovskite cell with a 17.88%-efficient top perovskite device and a 7.85%-efficient bottom antimony selenide bottom cell.

Chalcogenides are compounds formed primarily from chalcogen elements such as sulphur, selenium or tellurium ... glass (wavelengths of 2–6 μm) and selenide glass (wavelengths of 2–9 μm).

Cadmium selenide (CdSe) is an II-VI semiconductor material with a bandgap of around 1.7eV, which makes it ideal for building thin-film solar cells with strong optoelectronic properties ...

"There are three antioxidants that have been proven to decrease the effect of the sun on the skin and actually prevent further damage: selenium, vitamin E, and vitamin C." Antioxidants are known ...

and the Air Force Research Laboratory grew the 2D semiconductor indium selenide (InSe) on a full-size, industrial-scale wafer. It can also be deposited at temperatures low enough to integrate with a ...

Disadvantages: Gallium arsenide has no natural insulating layer to prevent impurities from shorting the cell. It is also expensive. Selenium is expensive and difficult to obtain and therefore too ...

Other materials that are less commonly used include lead sulfide (PbS), lead selenide (PbSe), and lead telluride (PbTe), although they react to infrared light, not the visible spectrum. CdS ...
