ANALISIS UJI KINERJA DYE SENSITIZED SOLAR CELLS (DSSC) MENGGUNAKAN VARIASI WARNA DARI BUNGA ANGGREK ENDEMIK INDONESIA

Abstract

This research is about the trial of dye sensitized solar cells (DSSC) using natural dyes, namely variations in the color of moon orchid flowers with the aim of identifying the effect of dyes from variations in the color of Indonesian endemic orchid flowers on dye sensitized solar cells (DSSC), knowing the highest peak power value of dye sensitized solar cells (DSSC) from extracts of various color variations of Indonesian endemic orchid flowers, knowing the best efficiency value of variations in orchid flower color samples using TiO2 semiconductors. The method used is the UV Vist test method to determine the level of absorption in the sample, Fourier Transform Infrared (FTIR) to analyze the functional groups contained in the sample, solar test and UV lamp to get the highest peak power value of the moon orchid flower color variation, and efficiency test to see the performance of the sample. The results of the tests that have been carried out obtained the highest peak power value is in the orange orchid sample solar light testing at minute 15 starting time 11:05 pm with sunlight intensity 1755 obtained voltage value 132.4 mV, current 0.406 mA, and power 5.38E-05 Watt, and for UV lamp testing the highest value is at minute 15 starting time 15:15 pm with UV lamp intensity 438 obtained voltage value 113.3 mV, current 0.323 mA, and power 3.66E-05 Watt. with the efficiency produced in irradiation 0 mwcm−2 with a fill factor (FF) value of 0 % and an efficiency value of 0 %, irradiation 50 mwcm−2 with a fill factor (FF) value of 24.6% and an efficiency value 5.7342E-05 %, and irradiation 100 mwcm−2 with a fill factor (FF) value of 24.3% and an efficiency value 4.8755E-02 %.
