本研究的目的是展示一种全喷雾倒置有机光致发光材料的制造工艺。我们喷涂了聚（3-己基噻吩-2，5-二基）和[6，6]苯基-C61-丁酸甲酯的共混物作为活性层，并通过溶胶-凝胶工艺制备了氧化锌作为电子传输层。高导电性的聚（3，4-亚乙基二氧噻吩）：聚（苯乙烯磺酸）作为一个透明的阳极和替代银依次喷涂。在这项工作中，我们进一步利用氮（N2）等离子体改性的有源层，以改善两层之间的兼容性。结合后续热处理工艺的调整，可以获得性能良好的全喷涂器件。通过优化N2等离子体和热处理工艺，获得了最高的功率转换效率（PCE）2.90%，并进行了稳定性测试。此外，我们将全喷涂工艺放大到具有三个串联电池的模块，并且模块的PCE达到2.44%。
The aim of this study is to demonstrate a fabrication process of all-sprayed inverted organic photovoltaics. We sprayed the blend of poly(3-hexylthiophene-2,5-diyl) and [6, 6] phenyl-C61-butyric acid methyl ester as an active layer and zinc oxide prepared by a sol–gel process as an electron transport layer. The highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) as a semitransparent anode and alternative to Ag is sequentially spray-coated. We further utilize nitrogen (N2) plasma modification on the active layer for improving the compatibility between two layers in this work. With a combination of tuning the subsequent thermal treatment, the all-sprayed devices with good performance could be obtained. The highest power conversion efficiency (PCE) of 2.90% is achieved by optimizing the N2 plasma and thermal treatment, and the stability test is performed. Moreover, we up-scaled the all-spray-coating process to a module with three cells connected in series, and the PCE of the module is achieved to 2.44%.
