     We report on the use of conductive polymer, polyaniline (PANI), as Hole Injection Layer (HIL) to fabricate organic solar cells. The effect of water-dispersity of the PANI, the variation of the PANI concentration film, the thickness of the PANI film and the influence of the addition of poly(acrylamid) into PANI in the performance of the cells are studied. I-V characteristics and energy conversion efficiency will be discussed.


Keywords: HIL; polyaniline; organic photovoltaic cells.
