Printed electronics have surfaced with a lot of interest recently. This paper reports development of a non vacuum process for fabricating poly(3-hexylthiophene):[6,6]-pheny-C61-butyric acid methyl ester organic solar cells (OSCs) using ink-jet printing technique. The printing conditions of different layers were optimized to avoid the coffee ring effect and the Marangoni effect. The effect of substrate's temperature and drop spacing size was compared to obtain uniform layers. We controlled the substrate temperature ranging from 30 degrees C to 80 degrees C and varied the spacing size between two lines ranging from 10 μm to 80 μm during printing. The device characteristics were analyzed using alpha step and solar simulator. The optimized printed conditions for ZnO are 50 degrees C substrate temperature and 50 μm spacing size. For the active layer,
PSS and Ag electrode, the optimized conditions are 50 degrees C/50 μm, 30 degrees C/30 μm and 80 degrees C/80 μm, respectively. The power conversion efficiency of the OSCs fabricated with optimized printing condition is 1.25%.
印刷电子技术最近引起了广泛关注。本文报道了一种使用喷墨印刷技术制造聚（3-己基噻吩）：[6,6]-苯基-C61-丁酸甲酯有机太阳能电池（OSC）的非真空工艺的进展。对不同层的印刷条件进行了优化，以避免咖啡环效应和马兰戈尼效应。比较了基板温度和墨滴间距尺寸的影响，以获得均匀的层。在印刷过程中，我们将基板温度控制在30℃至80℃之间，并将两条线之间的间距尺寸从10μm变化到80μm。使用台阶仪和太阳能模拟器分析了器件特性。ZnO的优化印刷条件是基板温度50℃和间距尺寸50μm。对于活性层、聚（3,4-乙撑二氧噻吩）：聚苯乙烯磺酸盐（PEDOT：PSS）和银电极，优化条件分别为50℃/50μm、30℃/30μm和80℃/80μm。采用优化印刷条件制造的有机太阳能电池的功率转换效率为1.25%。
