Dye-sensitized solar cells (DSSC) made of TiO2 have received considerable attention from many researchers for the last three decades. Rapid theoretical and experimental studies have been conducted to improve the performance of DSSC. To understand the DSSC internal parameters, we need to fine-tune each component and identify the suitable conditions in optimizing the performance of assembled devices. In this work, we analyzed and calculated of several parameters the DSSC photoanode, e.g. Electron diffusion and photon absorption coefficients. The experimental I-V data from solar simulator measurements were fitted base on electron diffusion model using Microcal Origin software. We compared the photon absorption coefficient values from this calculation method with the result of UV-Vis measurement and compared the electron diffusion coefficient values with the result of the SEM image data fitting calculation method. It was apparent that the results of I-V data fitting calculation method were comparable with the results of two other techniques. © Published under licence by IOP Publishing Ltd.
