KINERJA DYE-SENSITIZED SOLAR CELL (DSSC) MENGGUNAKAN MATERIAL BUNGA INDIGOFERA (INDIGOFERA TINCTORIA L.) DAN BUNGA TELANG (CLITORIA TERNATEA L.)

Abstract

This research is about dye-sensitized solar cell using natural ink solution derived from Indigofera (Indigofera Tinctoria L.) flower and Telang (Clitoria Ternatea L.) flower, which is tested for power, characterization, and efficiency. The methods used in this research are power testing with sunlight and UV light, Fourier Transform Infrared (FTIR) which aims to analyze the functional groups present in each sample solution from Indigofera flowers and Telang flowers, UV-Vis which aims to determine the absorbance ability of the sample at the peak of the wave, and IV-Curve which aims to determine the efficiency of each sample with different radiation intensities. The results show that Telang flowers have higher power than Indigofera flowers, and Telang flowers have an efficiency of 0.0025% and 0.05% for a radiation intensity of 50mW/cm2 and 100mW/cm2, respectively.
