Nano-structured amorphous carbon films using novel palm oil precursor for solar cell applications

摘要

The nano-structured of as-deposited (a-C) and boron-doPed amorphous carbon (a-C:B) films prepared from natural palm oil precursor for solar cell applications were presented. Field-emission scanning electron microscopy (FESEM) revealed films had particle size in the range of 28-59 nm. The energy-dispersive spectroscopy (EDS) showed the existing of carbon and boron on films was amorphous in nature by Raman spectra. Solar simulator analysis results showed an open circuit voltage (V-OC), current density (J(SC)), fill-factor (FF) and conversion efficiency (eta) of Au/a-C-Si/Au were 0.265V, 1.505 mA/cm(2), 0.327 and 0.1302%, respectively. Meanwhile, the V-OC,J(SC), FF and eta of Au/a-C:B-Si/Au solar cell were 0.272V, 14.92 mA/cm(2), 0.336, and 1.543%, respectively. The conversion efficiency was increased by boron doping to 1.543%.
