A new phthalocyanine grafted polymer namely 3, 3', 3'', 3'''-Tetra{ poly- (1, 4-

phenylene isophthalamide)} pthalocyanine copper (II) (TPPT) has been prepared and

characterized by IR , U.V-visible spectroscopies. 3, 3', 3'', 3'''-Tetra{ poly- (1, 4-

phenylene isophthalamide)} pthalocyanine copper (II) (TPPT) deposited at the interface

of the hole collecting buffer intermediate layer [poly(3,4ethylenedioxythiophene):

poly(styrene sulfonate) (PEDOT: PSS)] and poly (3-hexylthiophene): [6,6]-phenylC61

butyricacidmethylester (P3HT:PCBM) active layer were found to significantly increase

solar cell performance. The "photo-physical" properties of these devices incorporated

with (TPPT) with different space distributions at the interface of PEDOT: PSS buffer

intermediate layer, and P3HT: PCBM active layer were investigated. We find that, the

optical property was improved as the TPPT are large enough to penetrate into the active

layer and the performance of organic solar cells (OSCs) with large TPPT can benefit

from the improved hole collection efficiency. The power conversion efficiency (PCE)

enhancement for the device with a PEDOT: PSS. TPPT film is more significant than for

the device with PEDOT: PSS film. PSCs give Power Conversion Efficiency (PCE) of

0.14%, for ITO/PEDOT:PSS: TPPT/P3HT: PCBM/Al devices.
