Influences of Low Energy Ion Implantation onProperties of Polyaniline/Si Heterojunction Solar Cells

摘要

Ion implantation may favorably modify the properties of polyaniline/Si heterojunction solar cells fabricated by the electrochemical method. Influences of the implantation on the absorption spectrum and the thermal stability were discussed and output properties were measured. The results show that the absorption spectrum of the polyaniline films modified by ion implantation is much wider; its pyrolytic temperature increases by 40℃, and the polyaniline/Si cell efficiency increases 18 and 3 times under the illumination of （10.92） and 37.2W/m2, respectively.
