Further, the feasibility of the MOF film as a sensitizer in a solar cell is investigated. The HOMO-LUMO level of the frameworks is estimated and is found to be suitable to allow the use of the frameworks as a sensitizer for TiO2. When TiO2 mesoporous film is sensitized with the LBL thin film of the frameworks and a Gratzel type liquid junction solar cell is constructed, it demonstrates the cell performance of I-sc = 2.56 mA cm(-2), V-oc = 0.63 V, FF = 0.63, and E-ff = 1.22%. Photoluminescence spectroscopy and electrochemical impedance spectroscopy show that iodine doping into the frameworks is essential to facilitate the photogenerated electron transfer from the frameworks to TiO2.
