(Nanowerk News) Scientists are interested in improving the stability of a class of crystalline materials that, if more stable, could be the basis for inexpensive solar cells. These materials, called ...

Using a new pressure quenching (PQ) technique at high temperatures to induce superconductivity in iron selenide (FeSe) crystals, superconductivity was achieved -- and sustained -- without pressure. In ...

A Kuwait University research team compared the effects on perovskite film grain-size, crystallinity, surface roughness, defects, and related solar cell performance of helium and argon quenching gases ...

Quenching refers to the rapid cooling of a machined piece. The aim of quenching is to obtain certain required material characteristics by desired phase transformations. Quenching is dependent upon ...

The US National Renewable Energy Laboratory (NREL) has achieved remarkable efficiency and stability for a wide-bandgap all-perovskite tandem solar cell. The scientist developed the device with an ...
