摘要：

Lengthening the polymer solidification time in the inverted configuration of polymer/ZnO nanorod hybrid solar cells is studied as a way to improve device performance. As the polymer solidification time is lengthened by lowering the spin-coating rate of the photoactive layer, the photoactive layer becomes thickened, and the polymer chains have enough time to self-organize and effectively infiltrate into ZnO nanorod spacing. While the thickness of the photoactive layer is increased to 400 nm accompanying self organized polymer, the power conversion efficiency of the device is improved to 3.58% with all enhanced fill factor of 58%. The 400 nm film is composed of the highly ordered polymer and the ZnO nanorod arrays, resulting in light harvesting without decreasing the possibility for charge transport. (C) 2009 Elsevier B.V.
