Abstract
The study would investigate the effect of the scattering model on the photoelectric conversion efficiency for the silicon solar cell and dye-sensitized solar cell (DSSC). We will examine the accuracy of optical simulation of these solar cells by the A class standard measurement of AM1.5G at the light source of 1000 W/m2. The scattering lighting of DSSC always is occurred by the particle size of the titanium dioxide (TiO2) and the distribution of the layer. Anyway, the silicon solar cell would absorb the lighting by the energy band of the silicon. Therefore, the bidirectional scattering distribution function (BSDF) could descript the scattering status for the silicon solar cell and DSSC. The regular pattern of the cover glass including the type, size, deep and smooth would affect the scattering model of the silicon solar cell and DSSC for the absorption efficiency. We found the absorption efficiency would be enhanced at the scatter pattern of large deep and smooth. The scattering pattern in the front always was better than in the back for the cover glass at the efficiency of lighting absorption. The absorption efficiency of DSSC would be higher than the silicon solar cells at the same scattering pattern. The optical simulation and measurement results showing the absorption efficiency of DCCS was better than the efficiency of silicon solar cell.
