Study of the Electrical Characteristics of Poly(O-Toluidine) and Application in Solar Cell
چکیده انگلیسی
Substituted poly(o-toluidine) (POT) was synthesis by chemical polymerization method using ammonium persulphate as oxidizing agent. Thin fims of poly(o-toluidine) have been prepared by spin coating method and characterized by (FTIR) spectra and Atomic force microscope (AFM). Current-voltage characteristic of AL/POT/AL sample at different temperature (273-383)K is investigated .It is show ohmic behaviour at all applied voltage. The electrical conductivity increases with temperature increase from 1.49x10-7 S/cm at 293K to 6x10-6 S/cm at temperature 383K. This behaviour indicates that the POT polymer behaves as semiconductor material .The electrical conductivity as a function of reciprocal absolute temperature (1/T) was also investigation .The activation energy was obtained from the curve about (0.313 eV). (J-V) Characteristics of POT solar cell devices was studies. The open circuit voltage Voc is about 0.22 V at short circuit current about (1.7 mA/cm). The fill factor (ff) obtained is about (0.235). The POT/n-Si solar cells obtained in this work have yielded a conversion efficiency is about 0.88%.
