Abstract: (2383 Views)
In this paper, nanocrystal metal organic framework (ZIF-8) was synthesized and used in the fabrication of perovskite solar cells. ZIF-8 nanoparticles were coated on the mesoporuse TiO2 layer. Effect of thickness of ZIF-8 was investigated on the performance of perovskite solar cells. The cell with spin coating once exhibited the best performance with a short-circuit current density of 7.48 mA cm-2, open circuit voltage of 0.64 V, fill factor 0.56 and the highest photo-conversion efficiency of 2.71% under the illumination of 100 mw cm-2. Furthermore, optical parameters, structure and morphology of the ZIF-8 nanocrystals was studied using the appropriated instrumental techniques: SEM, XRD and UV-vis spectroscopy. The average crystallite size of ZIF-8 nanoparticles was estimated 63 nm by SEM that it agrees well with the value obtained from XRD.
