Abstract

A novel 8 V DC power source with an external series-parallel connection of 50 Dye-sensitized Solar Cells (DSCs) has been proposed. One DSC has the optimized length to width ratio of 5.2 × 2.6 cm and an active area 8 cm2 (4.62 × 1.73 cm) which attained a conversion efficiency of 4.02 %. From the electrochemical impedance spectroscopic analysis, it was found that the resistance elements related to the Pt electrode and electrolyte interface behave like that of diode and the series resistance corresponds to the sum of the other resistance elements. Surface morphology and sheet resistance of Pt counter electrode did not degrade the performance of the cell. This novel 8V-0.33A DC power source shows stable performance with an energy conversion efficiency of 4.24 % under 1 sun illumination (AM 1.5, Pin of 100 mW/cm 2).
