The influence of the crystalline orientation of the TiO2 photoanode on the photo-electrochemical characteristics was investigated to reveal the primary factors responsible for improving the photoelectric conversion efficiency of a dye-sensitized solar cell. It was observed that the photocurrent depended on the plane orientation, whereas the dependence of the photopotential on the open circuit was almost constant. The rate of the photoanodic reaction was attributed to the dye adsorption, depending on the surface energy of each oriented plane of the TiO2. The cathodic reaction on TiO2 during open circuit is likely to determine the rate of the entire electrochemical reaction.

Dye Sensitized

The efficiency of the best Dye sensitized solar cell is primarily depends on the good light harvesting property of the photo anode. Present study uses Lawsone (2 hydroxy [1, -naphthoquinone), the natural dye and compare the performance of photo anode in bare TiO2 and with nanoporous CaCO3 coated TiO2. As compared to bare TiO2, the surface area of nanoporous CaCO3-coated TiO2 increases, consequently, a better amount of dye adsorption occurs. The coating of CaCO3 increases the impedance at TiO2/dye/electrolyte interface and affect lifetime of the photoelectrons. Due to this reasons the short circuit current Jsc, open-circuit voltage (Voc), and fill factor (FF) increases. Thereby, the energy conversion efficiency of the solar cell is improved.

Viable Method

Dye adsorption on Ti02and electron transport in Ti02film are the two critical factors in determining efficiency of the the dye sensitized solar cell (DSSC). Increasing dye adsorption which increases the light harvesting is usually achieved by using nanoporous or nanoparticle Ti02films. Electron transport is determined by the inter-particle resistance of Ti02film. Electrospinning is a viable method for forming porous structure materials with high surface area. In this study, it was found that electrospinning is able to achieve good solar cell performance due to the high electron transport caused by the pores in the Ti02film.

Dye-sensitized solar cell (DSSC) is being extensively investigated as the next generation energy source. Despite of the attractive features like simple fabrication process and its economic efficiency, there are some problems such as low efficiency, long fabrication time and low long-term stability. Conventionally, the dye adsorption on TiO2 photo-electrode film needs long time in the solvent with low concentration of dye to get the high efficiency. In this work, the dye coating process was considerably shortened, albeit plenty of dye was used comparing with the conventional way. Our needs were met for the best result in our working environment and the relevant conditions to our work were obtained, which were the coating temperature of 70 °C, the dye concentration of 10 mM and the coating time of 3 min. And this coating process was successively repeated several times to maximize the dye adsorption and to improve the cell efficiency. Therefore, the efficiency increased by 13% in the proper condition.
