我们报告了在玻璃和塑料基板上的高性能透明铜栅电极，其提供比传统氧化铟锡电极更高的Haacke品质因数，并且与有机光致发光器件（OPV）的要求很好地匹配。该电极是使用微接触光刻与分子抗蚀剂和低毒性蚀刻剂的组合，即十六烷基硫醇和过硫酸铵水溶液。这种电极制造方法比传统的光刻快得多，因为它比使用传统的金属印刷方法可能的要窄20倍，因此网格间距
We report high-performance transparent copper grid electrodes on glass and plastic substrates that offer a higher Haacke figure-of-merit than conventional indium tin oxide electrodes and are well-matched to the requirements for organic photovoltaics (OPVs). The electrode is fabricated using microcontact lithography with a combination of molecular resist and low toxicity etchant, namely, hexadecanethiol and aqueous ammonium persulfate. This approach to electrode fabrication is much faster than conventional lithography because it takes 20 times narrower than is possible using conventional metal printing methods and so a grid pitch
