الوصف الكامل (Full Abstract)
The effects of metal chlorides such as LiCl, NaCl, CdCl2 and CuCl2 on optical transmittance, electrical conductivity
as well as morphology of PEDOT:PSS films have been investigated. Transmittance spectra of
spun PEDOT:PSS layers were improved by more than 6% to a maximum of 94% in LiCl doped
PEDOT:PSS film. The surface of the PEDOT:PSS films has exhibited higher roughness associated with an
increase in the electrical conductivity after doping with metal salts. The improvement in the physical
properties of PEDOT:PSS as the hole transport layer proved to be key factors towards enhancing the
P3HT:PCBM bulk heterojunction (BHJ) solar cells. These improvements include significantly improved
power conversion efficiency with values as high as 6.82% associated with high fill factor (61%) and larger
short circuit current density (18 mA cm2).
