Effects of HSQ4 Concentration into dyes of Carica Papaya on the Performance of Dye-Sensitized Solar Cell

Abstract

Organic dyes are very important in improving the performance of solar cells, at very low prices and friendly to the environment. DN-F15 transparent green is a squaraine dye with good stability on DSSC or with an alternative name HSQ4. HSQ4 is a synthetic dye that is very expensive, but sensitive to light so that it can improve the performance of solar cells. DSSC uses titanium dioxide (TiO2) as a semiconductor, electrodes are used as substrates for the flow of electric charge. DN-EP01 is a thixotropic terpineol-based screen-printable Pt paste with a viscosity of 4-7 Pa.s at 10s−1. In furnaces around 450°C will produce an even and transparent platinum particle layer which has high catalytic activity. The color of the platinum paste is straw or light yellow. Measurement of absorbance dyes solution using a spectrophotometer with a wavelength of 400 nm -800 nm. Characterization of I-VDSSC Carica Papaya produced a V ocvalue of 560 mV, Isc 1.5 x 10−4 A, fill factor 0.47 and efficiency of 0.43%. After doping with HSQ4 the concentration of 1 resulted in a Voc value of 378 mV, Isc 4.0 x 10−4 A, fill factor 0.49 and efficiency of 0.14%. An increase in efficiency in variation 3 is 0.24% and variation 5 is 0.35%, this shows the effect of HSQ4 concentration on the coloring of papaya leaf extract can improve the performance of DSSC.
