Since the discovery of the photovoltaic effect in bulk heterojunction
devices¡Mthe considerable publications in PSCs have been reported¡OPSCs
based on the concept of bulk heterojunction (BHJ) configuration where
active layer comprises of a p-type donor (conjugated polymer) and a n-type
acceptor (fullerene derivative) materials¡Mrepresents the most useful strategy
to maximize the internal donor-acceptor interface area allowing for efficient
charge separation¡OTo further enhance the power conversion efficiency
from solar cells made of poly(3-hexylthiophene)/[6,6]-phenyl C61 butyric
acid methyl ester (P3HT/PCBM) ¡M a new conducting polymer with
optimized band energy levels are demonstrated to be one of the key
properties¡OIn this study¡MI synthesized a soluble and strongly visible-light
absorbing alternating conducting polymer using Suzuki coupling
polymerization method¡OThe UV-Vis absorption spectra of copolymer contains an intramolecular charge transfer (ICT) transition band¡Mwhich
leads to absorption extending to near-infrared region and optical band gaps
is 1.55 eV¡OThe photo-electron spectroscopy in air(PESA) measurements
show that the HOMO level of the polymer is ~5.0eV which is lower than
P3HT¡O
