High-performance inverted polymer solar cells with solution-processed titanium chelate as electron-collecting layer on ITO electrode

Adv Mater. 2012 Mar 15;24(11):1476-81. doi: 10.1002/adma.201104863.

Abstract

High-performance inverted polymer solar cells (PSCs) with solution-processed titanium chelate TIPD as electron collecting layer are reported. The power conversion efficiency (PCE) of the inverted PSC with a-TIPD buffer layer with thermal annealing at 150 °C for 10 min reached 7.4% under the illumination of AM1.5, 100 mW/cm(2), which is increased by 16% in comparison with that (6.4%) of the device in the conventional structure. The PCE of 7.4% is the highest among the inverted PSCs reported so far in the literature.
