Fabrication of Dye Sensitized Solar Cells Using Electrostatically-Injected Droplet Method Induced

Dye-sensitized solar cells (DSCs) have attracted great attention in academic research and industrial applications because of their high efficiency and the potentials for flexible and low-cost solar cells.1 As shown in figure 1, DSC typically consists of a dye-adsorbed nanocrystalline titanium dioxide (TiO2) electrode, an organic electrolyte containing an iodide/triiodide redox couple and a platinum-coated counterelectrode. In general, patterned TiO2 layer is important for energy conversion efficiency of DSC device and printing techniques such as doctor blade and screen printing are used to develop nanocrystalline TiO2 electrode. In this study, we try to use inkjet printing technique to develop nanocrystalline TiO2 layers. Inkjet print technique is one of the most popular and promisin
