title = "Performance improvement of dye-sensitized solar cell by introducing Sm3 +/Y3 + co-doped TiO2 film as an efficient blocking layer",
abstract = "Luminescence mediums: samarium ion and yttrium ion, were introduced to expand the photo-response region of TiO2 by means of the down-conversion effect to convert ultraviolet light into visible light, offering a unique method to enhance the photovoltaic performance of dye-sensitized solar cells (DSSCs). Their crystal structures, optical properties as well as photovoltaic performance were investigated systematically. The result indicates that the DSSCs doped with a total molar ratio of 4 mol% of Sm3 + and Y3 + show an overall power conversion efficiency of 4.09%, which is equivalent to improvements of 17.52% and 16.2% as compared to the no blocking layer DSSCs and pure TiO2 blocking layer DSSCs respectively. The improvement in conversion efficiency is attributed to the dual effects including down-conversion of ultraviolet light and reduction of electron-hole recombination rate.",
