Researchers have confirmed the chemical inertness of PtSe2 surfaces to ambient gases (oxygen and water) and, as a result, the long-term durability of PtSe2-based devices using synchrotron-based surface-science methods.
Researchers have built a thermoelectric generator that generates electricity from the difference in temperature between the PV cell and the surrounding environment. This research has been published in Applied Physics Letters.
Wu, J. et al.'s study discusses a low-threshold on-chip perovskite polariton parametric oscillator using all-inorganic CsPbBr3 microcavities at ambient temperature.
