Abstract: (1451 Views)
In this study, meta-organic framework based on Al (MIL53) nanocrystals were used as an interlayer in conjunction with the perovskite film and electron transporting layer to surface modification of the perovskite layer and improve charge transfer in the solar cell structure. The optical and electrical characterization show that the MIL53 on the mesoporous TiO2 layer can acts as scaffold for crystallization of perovskite layer with lower defect concentration and auxiliary light absorbing layer at the short-wavelength range, leading to improved photovoltaic performance of the perovskite solar cells. As a result, the power conversion efficiencies of the hole transport material (HTM) free perovskite solar cells with the structure of FTO/TiO2/CH3NH3PbI3/Au is increased 1.5% when MIL53 is present. This study demonstrates the promising potential of using MIL53 to fabricate efficient PVSCs.
