喷墨印刷用于沉积适合作为有机太阳能电池活性层的聚合物：富勒烯混合物。我们表明，单独沉积的墨滴合并成连续的、无针孔的有机薄膜是由于墨水粘度和表面润湿之间的平衡而产生的，而对于某些研究的解决方案，单个墨滴会出现明显的咖啡滴效应；对于较大的印刷区域，可以将这种情况最小化，从而产生具有最小表面粗糙度的光滑层。所得有机薄膜用作太阳能电池的活性层，在模拟 AM1.5 太阳光照下，功率转换效率为 1.4%。 (C) 2008 年美国物理研究所。
Ink-jet printing is used to deposit polymer:fullerene blends suitable as active layer for organic solar cells. We show that merging of separately deposited ink droplets into a continuous, pinhole-free organic thin film results from a balance between ink viscosity and surface wetting, whereas for certain of the studied solutions clear coffee drop effect occurs for single droplets; this can be minimized for larger printed areas, yielding smooth layers with minimal surface roughness. Resulting organic films are used as active layer for solar cells with power conversion efficiency of 1.4% under simulated AM1.5 solar illumination. (C) 2008 American Institute of Physics.
