Abstract
Abstract The complex and nano-structured amorphous carbon as p-type films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy FESEM revealed the nano structured films had particle size in the range of 28 to 34 nm. The energy-dispersive spectroscopy EDS showed the existing of carbon in complex-structured amorphous carbon film and carbon together with boron in nano-structured amorphous carbon film. Solar simulator analysis results showed an open circuit voltage VOC current density JSC fill-factorFF and conversion efficiency 26951 of Aua-Cn-SiAu were 264.62 mV 1.50434 mAcm2 0.32632 and 0.130154 respectively. Meanwhile the VOC JSC FF and 26951 of Aua-CBn-SiAu solar cell were 271.25 mV 14.91723 mAcm2 0.33582 and 1.542622 respectively. The conversion efficiency was increased as the p-type a-CB film in the nanostructured form.
