In this work, studies were made to improve the photoelectrical characteristics of the dye-sensitized solar cells (DSSCs) with undoped and Al, B doped ZnO blocking layers (BLs) placed at the interface of SnO2:F (FTO) material and porous TiO2 layer. The BLs were prepared by sol-gel method and deposited onto FTO surface by using spin coating technique. TiO2 paste was applied onto the blocking layer by Doctor Blade method to form the working electrodes (WEs) of the DSSCs. Wild jasmine (jasminum fruticans) and mahaleb cherry fruit (Prunus mahaleb) extracts were used to sensitize the porous TiO2 layer. Our findings demonstrated that the application of Al and B-doped ZnO BLs between TiO2 layer and FTO improves the solar photovoltaic electrical characteristics.
