Data Analysis for Several Dye-Sensitized Solar Cells Tested at Different Wavelengths and Lighting Conditions

The primary option for harvesting electrical energy from indoor illumination conditions with very low illuminance levels is dye-sensitized solar cell (DSSC). In this paper, six dye-sensitized solar cells with complex structures based on titanium dioxide $\left(\mathrm{TiO}_{2}\right)$ were examined to understand their distinct characteristics. Through an experimental investigation, an attempt is made to understand the behavior of DSSC under different illumination conditions and types of connections. The experiment was performed inside an integrated sphere detector, and the light parameters were measured using a spectroradiometer. The electrical properties of all six DSSCs were described by testing them individually, in series, or in parallel with the other cells. A programmable RGB bulb was used to modify the illumination and wavelength conditions.
