Characterization of dye-sensitized solar cell (DSSC) based on chlorophyll dye

Performance of Dye-Sensitized Solar Cell (DSSC) based on chlorophyll dye that extracted form papaya and jatropha leaves was analyzed in this paper. The optical and electrical characterization DSSCs were investigated using solar radiation and under variation of light illuminations. A sandwich structure was designed by 2x2 cm active area of TCO which has a surface sheet resistivity of 15-25 ohms/sq. Photo-electrode layer using TiO₂ paste is deposited using doctor-blade technique and the counter electrode layer substrate coated with carbon that produced by candle. The parameters that affect to the electrical characteristics of the solar cells were also analyzed and measured using cool daylight and warm white LED. The output DSSC of papaya leaves chlorophyllbased was achieved when Air Mass 1.5 at 8:38 am under solar radiation of Voc and Isc are 393.8 mV and 60 μA, respectively. Thee I-V characteristic was obtained fill factor of 24.9%. Measured electrical characteristic between two lamps indicated that the cool daylight LED was produce the Voc and Isc greater than warm white LED. The output voltage and current response both of two lamps were investigated increasing exponentially.
