Abstract: (827 Views)
In this research, nanocrystals of metal-organic frameworks (MOF), based on metal ions of aluminum, bismuth, cobalt, chromium, copper, tin, titanium and zinc with homogenous morphology were synthesized using a solvo-thermal method as an organic framework to form the porous MOF-doped TiO2 for electron transport layer in perovskite solar cells. By thermally decomposing the MOF-doped TiO2 layer in air, the organic template was removed, and porous MOF-doped TiO2 was obtained. The results of optical properties of crystal structure of porous MOF-doped TiO2 layer showed that doping with MOF remarkably improved the absorption ability of TiO2-MOF layer toward the Uv-Vis region with band gap energy less than of 2.7 eV. The photoluminescence spectroscopy was conducted to illustrate the improvement of electron transfer in the doped material further. The power conversion efficiency of solar cells using MOF-doped TiO2 was found to improve in comparing that of solar cells using pristine mp-TiO2.
