Surface recombination strongly influence on the photoconductivity decay curve. In this work it was shown that usually defined using this curve the effective life time don’t achieve maxima value if silicon sample thickness exceeds six diffusion length. In this case well known formulas for calculation of free carrier recombination lifetime need to be adjusted.

A chitosan binder-based TiO2photoelectrode is used in dye-sensitized solar cells (DSSCs). Field-emission scanning electron microscope (FE-SEM) images revealed that the grain size, thickness, and distribution of TiO2films are affected by the chitosan content. With addition of 2.0 wt% chitosan to the TiO2film (D2), the surface pore size became the smallest, and the pores were fairly evenly distributed. The electron transit time, electron recombination lifetime, diffusion coefficient, and diffusion length were analyzed by IMVS and IMPS. The best DSSC, with 2.0 wt% chitosan addition to the TiO2film, had a shorter electron transit time, longer electron recombination lifetime, and larger diffusion coefficient and diffusion length than the other samples. The results of 2.0 wt% chitosan-added TiO2DSSCs are an electron transit time of  s, electron recombination lifetime of  s, diffusion coefficient of  cm2s−1, diffusion length of 14.81 μm, and a solar conversion efficiency of 4.18%.

A comparative study has been made to analyze the impact of interstitial iron in minority carrier lifetime of multicrystalline silicon (mc-Si). It is shown that iron plays a negative role and is considered very detrimental for minority carrier recombination lifetime. The analytical results of this study are aligned with the spatially resolved imaging analysis of iron rich mc-Si.
