Characterization of iodine doped amorphous carbon thin film using natural precursor / Rais Rahimi Ishak

The amorphous carbon thin films and iodine doping was prepared by thermal Chemical Vapor Deposition (CVD) method onto glass substrate. For amorphous carbon thin film deposition, camphor oil was used as natural carbon source precursor and iodine was used as p-type dopant for doping process. The effects of iodine doping duration from 0 minutes to 30 minutes on the structural, optical and electrical properties for carbon based solar cell applications have been investigated. The iodine doped amorphous carbon thin films were characterized by using Raman spectroscopy and FESEM for structural properties. UV-VIS-NIR spectroscopy and current-voltage (I-V) measurement were carried out for optical and electrical properties respectively.
