Abstract

The micro-structured of as-deposited (a-C) and nano-structured boron-doped amorphous carbon (a-C:B) films prepared from natural palm oil precursor for heterojunction solar cell were presented. Field-emission scanning electron microscopy (FESEM) revealed the micro and nano structured films had particle size in the range of 382 nm to 689 nm and 28 to 34 nm, respectively. The energy-dispersive spectroscopy (EDS) showed the existing of carbon in micro-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-factor(FF) and conversion efficiency (η) of Au/a-C/n-Si/Au were 264.62 mV, 1.50434 mA/cm2, 0.32632, and 0.130154 %, respectively. Meanwhile, the VOC, JSC, FF and η of Au/a-C:B/n-Si/Au solar cell were 271.25mV, 14.91723 mA/cm2, 0.33582, and 1.542622 %, respectively. The conversion efficiency was increased as constant negative bias of -20 V applied for doping boron into a-C film.
