Abstract
Organic solar cells have been made using the material poly (3-hexylthiophene)(P3HT), [6, 6]-phenyl-C61-butyric acid methyl ester (PCBM), and Chlorophyll-a with blend metods. Active layer of P3HT:PCBM:Chlorophyll-a are deposited using spin coating with rotary speed of 2500 rpm for 10 seconds and subsequently heated at 1000C for 10 min. Mass of chlorophyll-a are 0.1 mg, 0.2 mg, and 0.3 mg. Thin layers are characterized by UV-Visible Spectrometer Lamda 25 for optical properties and Keithley 2602 for electrical properties. From the UV-Vis showed that absorbance of P3HT:PCBM:Chlorophyll-a are 400-614nm and 620-700 nm. Efficiency of P3HT:PCBM:Chlorophyll-a for mass chlorophyll 0.1 mg, 0.2 mg, and 0.3 mg are 2.68 x 10-2 %, 3.93 x 10-2 %, and 8.79 x 10-2 % respectively.
