Modeling and performance analysis of dye-sensitized solar cell based on ZnO compact layer and TiO2 photoanode

Renewable energy, especially solar energy is a vital alternative solution to power challenge in these present times. More recently, dye-sensitized solar cells (DSSC) play an important role in solar power generation. The performance of DSSC can be increased by adding more cells to a cell stack in a Tandem cell with a separate band gap. A double-layer structured DSSC was analyzed in this study in which ZnO and TiO2 composite photo-anodes were prepared on Fluorine-doped tin oxide. Photovoltaic properties such as current-voltage (I-V) and photocurrent density-voltage curves were investigated for different thickness, absorption coefficients, and wavelengths. DSSC solar cell characterization technique such as I-V measurement was analyzed to evaluate the cells performance. The experimental results show an approximate increase in current of 0.02 A causing the I-V characteristics to change significantly when ZnO and TiO2 are combined. In addition, it was observed that as the J-V characteristics of TiO2 varies with electrode thickness, the current densityJscincreases simultaneously and reaches its peak point at 10 lm.
