Abstract

Poly(diallyldimethylammonium chloride) (PDAC), a water-soluble polyelectrolyte, is used as the electron collecting layer (ECL) on indium tin oxide (ITO) for inverted polymer solar cells (PSCs) with poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C71-butyric acid methyl ester (PC₇₁BM) as the active materials. PDAC is coated directly on top of the ITO using a simple solution processing. The work function (WF) of the ITO is dramatically reduced by dipole formation between the cationic amine of the PDAC and the anionic oxygen of the ITO. A reduction of the ITO WF improves the electron selectivity. As a result, the inverted PSCs with PDAC as an ECL exhibited a power conversion efficiency of 2.65% under AM1.5G illumination, which is significantly higher than that of the control inverted PSC with blank ITO (no ECL) and comparable to that of the control inverted PSC with ZnO ECL.
