A multilayer TiO2 film featured with gradual scattering structure was developed and used as photoelectrode for dye-sensitized solar cells. This structure of film consists of P25 nanoparticles and TiO2 aggregate which was synthesized by micro-emulsion method as scattering centers The scattering centers were deposited by gradually increasing the amount from the film’s bottom to its top. The special films were used for the studies on the photovoltaic performance of N719 and Zn-3, and their photoelectric conversion efficiencies were 7.34% and 4.04%, respectively. Furthermore, more improvement of the conversion efficiency is realized for Zn-3 than for N719 by using our newly developed multilayer films as photoelectrode compared with ordinary photoelectrode.

Abstract In the last two decades, dye sensitized solar cells (DSSCs) have gotten a lot of attention from researchers and have progressed quickly. To promote commercialization and large-scale application of DSSCs, their efficiency should be increased. This paper details significant advancements in advanced NiMoS3/BC nanocomposites for improving photoanodes and DSSC conversion efficiencies. The fabricated electrode samples were characterized by XRD, SEM, TEM, Raman, UV, PL and BET to explore the structural, morphological and optical properties. A significant reduction band gap with enhanced light absorption and rapid prevention of electron hole pair was explored by UV-DRS and PL studies. The photocurrent density-voltage (J-V) and IPCE characteristics were analyzed for assembled solar cell. The NiMoS3/BC (NMSC5) nanocomposite DSSC showed a PCE of 8.85%, far higher than that of the NiMoS3 (2.45%) and a PCE value equivalent to Pt CE (4.79 %). The enhanced PCE of the proposed electrodes are also discussed in scientifically.
