Control of grain size in sublimation-grown CdTe, and the improvement in performance of devices with systematically increased grain size [PDF]

open access: yes, 2010
A method to control the grain size of CdTe thin films deposited by close space sublimation using chamber pressure is demonstrated. Grain diameter is shown to increase in the pressure range 2–200 Torr, following the linear relationship D (?m)=0.027×P ...

Caging Polyhalide Anions in Polycyclodextrin for Long‐Lasting Aqueous Zinc‐Iodine Batteries

open access: yesAngewandte Chemie, EarlyView.
We demonstrated poly(β‐cyclodextrin) gel as an ideal host material that effectively contains and releases polyhalide anions in aqueous zinc‐iodine batteries. Such a unique host‐guest chemistry prevents the shuttle effect of polyhalides. The corresponding batteries can operate via both 2e and 4e storage, attaining 60,000 cycles with more than 99% and 85%
