Abstract: (1657 Views)
The effect of the Al2O3 thin film on photovoltaic characteristics of perovskite solar cells is studied. The thin film of the Al2O3 is deposited on mesoporous TiO2 by a rotational angular reactive sputtering method. The considered perovskite solar cells have the normal architecture of FTO/c-TiO2/mp-TiO2/CH3NH3PbI3/spiro-OMeTAD/Au. The increase of Al2O3 thickness leads to higher open circuit voltage. However, the current densities of the fabricated solar cells are reduced due to insulating characteristics of Al2O3. Here, solar cells with 15 nm thickness of Al2O3 present the best performance among the three different thicknesses studied.
