English Effect of Activated Variations Carbon from Oil Palm Empty Fruit Bunch to Solar Cell Efficiency p-n Junction Layer Cu2O-TiO2.

Abstract

Research about influence effect of activated activated carbon from oil palm empty fruit bunch to solar cell efficiency p-n junction layer Cu2O-TiO2 and direct of sunlight. The layer of Cu2O formed from copper (Cu) burned with temperature 550 ͦ C in 100 minutes. The solar cells are made with TiO2 layer composed of activated carbon from oil palm empty fruit bunch of 0%, 10%, 15%, dan 20%. The parameters of the solar cell can be obtained by measuring the short circuit (Isc), voltage open circuit (Voc), maximum power and Fill Factor (FF) with resitor value (R) 0-50 kΩ. The composed of TiO2 /activated carbon from oil palm empty fruit bunch analyzed using X-Ray Diffraction (XRD) and and Fourier Transform Infrared (FTIR) Spectrocopy. As a result addition of activated carbon from oil palm empty fruit bunch to solar cell efficiency is increase in the value, voltage and efficiency of solar cells. The results of the measurement of the highest efficiency of solar cells using a sun simulator and sunlight are found in variations of activated carbon 20%, with each efficiency values 0,043% and 0,0018%.
