Azo molecules are one of the fascinating organic molecular architectures with azo bond (-N=N-). Since the last century, the bright colored azo molecules are used as dyes for printing, food, paper, cosmetic laser, electronics, optics, material sciences etc. After the discovery of Prontosil as an antibacterial drug, azo molecules became into…[Lees meer]

The all-inorganic CsPb(I x Br1-x)3 (0 ≤ x ≤ 1) perovskite solar cells (PSCs) are attractive by virtue of their high environmental and thermal stability. Nevertheless, multiple-step deposition and high annealing temperature (>250 °C) and the structural and optoelectronic properties changes upon temperature-dependent phase-transition are pote…[Lees meer]
