Inverted non-fullerene organic solar cells: Charge carrier extraction and interface characterization

我们项目的第二阶段计划再持续两年，我们计划解决两个主题，以继续第一阶段开始的工作：1)具有系统不同水平电掺杂的金属氧化物电子萃取层。2)等离子体敏化电子萃取层作为电掺杂的补充方法。对于这两者，我们打算用同步加速器光电子能谱揭开富勒烯受体的能量排列，并将这些结果与器件（太阳能电池和专用单极器件）的特性联系起来。我们将明确研究C60和C70（以及PC60BM PC70BM），以测试我们的结果在更广泛的供体/受体光活性系统中的适用性。

For the second phase of our project planned to last another two years, we plan to tackle two topics in continuation of the work begun of phase one:1) Metal-oxide electron extraction layers with systematically varied levels of electrical doping.2) Plasmonically sensitized electron extraction layers as a complementary approach to electrical doping.For both, we intend to unravel the energetic line-up with fullerene acceptors using synchrotron photoelectron spectroscopy and to correlate these results to the characteristics of devices (solar cells and dedicated unipolar devices). We will explicitly study both C60 and C70 (and PC60BM PC70BM) in order to test the applicability of our results to a broader range of donor/acceptor photoactive systems.
