We present an efficient triple-tandem polymer solar cell with identical poly(3-hexylthiophene) (P3HT) and 1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C(61) (PCBM) bulk heterojunction as the active layers and highly transparent Al (1 nm)/MoO(3) (15 nm) as the intermediate layer. This intermediate layer is structurally smooth as characterized by atomic force microscopy. Although identical organic active layers are used to construct such triple-tandem cell, a tripled open-circuit voltage of 1.73. V and power conversion efficiency of 2.03% are obtained under simulated solar irradiation of 100 mW/cm(2) (AM1.5), demonstrating a viable technique for fabricating triple-tandem polymer cell with the intermediate layer of Al/MoO(3).
