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

对于我们计划再持续两年的项目的第二阶段，我们计划继续第一阶段的工作来解决两个主题：1）具有系统变化的电掺杂水平的金属氧化物电子提取层。2）作为电掺杂的补充方法的等离子体敏化电子提取层。对于这两个，我们打算使用同步光电子能谱来解开富勒烯受体的能量线，并将这些结果与器件（太阳能电池和专用单极器件）的特性相关联。我们将明确研究C60和C70（和PC60 BM PC 70 BM），以测试我们的结果的适用性，以更广泛的供体/受体光敏系统。

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.
