In this work, by casting water-soluble ammonium anthracene on metal oxides, the organic surface modifier re-engineered the interface of the metal oxide to improve charge transport. The energy level of ammonium anthracene increased the work function of indium tin oxide (ITO), functioning as a hole-blocker (electron-transporter). Solar cells in which ITO was treated by the ammonium anthracene produced an average power conversion efficiency (PCE) of 5.8% without ZnO, the electron-transporting layer. When the ammonium anthracene was applied to ZnO, an average PCE of 8.1% was achieved, which is higher than the average PCE of 7.5% for nontreated ZnO-based devices.
在这项工作中，通过将水溶性蒽铵 casting 在金属氧化物上，有机表面改性剂重新设计了金属氧化物的界面，以改善电荷传输。蒽铵的能级增加了氧化铟锡（ITO）的功函数，起到了空穴阻挡层（电子传输体）的作用。ITO 经蒽铵处理的太阳能电池在没有氧化锌（电子传输层）的情况下，平均光电转换效率（PCE）为 5.8%。当将蒽铵应用于氧化锌时，平均 PCE 达到 8.1%，高于未经处理的基于氧化锌器件的平均 PCE7.5%。
