摘要

We report efficient inverted polymer solar cells (PSCs) based on poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl-C)_(61)-butyric acid methyl ester (PCBM) using alcohol-soluble titanium (diisopropoxide) bis (2,4-pentanedionate) (TIPD) as an electron selective layer between the indium tin oxide (ITO) electrode and the photoactive layer. The thermally annealed TIPD layer is highly transparent in the visible range and shows effective electron collection ability. By optimizing the electron-collecting layer, the photoactive layer and the hole-collecting layer, the power conversion efficiency (PCE) of the inverted device with the structure ITO/TIPD/P3HT:PCBM/MoO _3/Ag reaches 4.10% under the illumination of AM1.5G, 100mWcm ~2, which is among the highest values for inverted PSCs based on P3HT:PCBM. The PCE of the inverted device is improved in comparison with the conventional device (3.77%) under the same experimental conditions.
