Dye Sensitized Solar Cells (DSSC), the third generation of photovoltaic devices, can be considered as most promising among renewable energy sources. Although DSSCs are devices very easy to fabricate, there is a large number of design parameters upon which their performance depends. In this review paper a lay out is given of the various parameters at which research groups focus aiming towards optimum...
The microstructure of the metal semiconductor oxide which forms the heart of a dye-sensitized solar cell (DSSC) has proved to play a key role in the enhancement of photoelectric conversion efficiency of the cell. In this work, a numerical simulation of the system TiO2 photo-sensitive dye of a TiO2 DSSC focuses on the effect that the oxide porosity and the size of the pores have on the cell's performance...
The system TiO2–photo sensitive dye of a dye-sensitized TiO2 solar cell is numerically simulated. The steady-state numerical model used is based on the continuity and transport equations for all charge species involved in the system, in connection to Poisson’s equation. The dependence of both electron diffusion coefficient and light absorbance upon TiO2 porosity is taken into consideration. The resulting...
