Abstract: For physical structure of TiO₂ films is the core of photoelectric conversion on the photovoltaic performance of DSSC, the method by parameter estimate to determine the optimal thickness of DSSC working electrode is deduced, which is consistent with the analysis of real physical meaning about the TiO₂ layer thickness and the photocurrent, while gives the specific optimal value as an addition. As a mathematical proof of the optimal conclusion extracting from the complex working mechanism of DSSCs and accidental factors, the equivalent circuit parameters of each curve are estimated corresponds to the equivalent circuit method first. According to the inflection point, which obtained through the synthesis of scattered experment points to the trend curve, the optimal thickness of DSSC working electrode are optimal identified.

Abstract: The way to determine the optimal solids content of TiO2 in DSSC working electrode was discussed. As a mathematical proof of the optimal conclusion extracting from the complex working mechanism of DSSCs and accidental factors, the equivalent circuit parameters of each curve are estimated corresponds to the equivalent circuit method first. And then, the trends in each parameter are analyzed. According to these trends, the optimal solids content of TiO2 are optimal identified

Abstract: By analyzing the transmitionce and heat rate of insulating antireflection films conposed by refractive-index adjustable SiO2 layer and TiO2 layers, the optimum combination of antireflection films of BIPV is obtained. The absorption rate at the ultraviolet part that wavelenght excessive inadequate 400nm of the optimized fils is 99.9%, which are directly designed on the surface of the low iron tempered glass panel of BIPV, and in the wavelength range 400nm-800nm, the visible light transmitionce rate is up to 99.5%, and the heat that wavelenght excessive 800nm is reflected of 20%. For the multilayer heat insulation films are composed with the same kind of material while with different refractive indexes, there is no projecting stress between these films and no constraints during the production process of different films for the possible low cost heat insulating of BIPV.

Abstract: The process of TiCl₄ treatment on the FTO substrate of DSSC were analyzed and the microstructures of substrates before and after treatment were observed. Further more, the influence of TiCl₄ treatment on the substrate of Dye-sensitized solar cell to photo-current voltage performance was numerical analyzed.
