Hybrid‐perovskite‐based optoelectronic devices are demonstrating unprecedented growth in performance, and defect passivation approaches are highly promising routes to further improve properties. Here, the effect of the molecular ion BF4−, introduced via methylammonium tetrafluoroborate (MABF4) in a surface treatment for MAPbI3 perovskite, is reported. Optical spectroscopy characterization shows that...
We report facile, one step synthesis of disordered graphitic carbon by high temperature (1000°C) pyrolysis of indanthrone dye (ID). The pyrolysed carbon is disordered in nature and the same is clearly evidenced by various analytical techniques like X-ray diffraction, Raman spectroscopy and high resolution transmission electron microscopy. Na-insertion properties of such indanthrone dye derived disordered...
