A comprehensive device modeling of solid state dye sensitized solar cell with SCAPS-1D

SCAPS-1D model of a Dye-sensitized solar cell (DSSC) is given and discussed. It is deduced from an experimental investigation results. In DSSC, the electrolyte provides the oxidized dye regeneration and the hole transport towards the photocathode. Evaporation of the liquid electrolyte under illumination and versus time is one of the defects and limitation of the DSSCs. Against part; solid-state transport materials presented more advantages. In this investigation, the proposed model studies the DSSC by considering the electrolyte liquid as a single solid p-type layer considered as a hole transporting materials and the TiO2 layer as electron transporting materials. SCAPS used in this work for studies the effect of absorber layer thickness, a semiconductor gap, doping density, series and shunt resistor on the main electrical parameters of the DSSC. In addition, temperature and irradiance effect are also investigated. The results show that the doping density, temperature and band gap energy of player influence on the properties of the cell.
