| 摘 要： | 本文讨论了喷墨印刷氧化铟锡（ITO）电极在有机太阳能电池（OSCs）中的应用。利用纳米ITO晶体进行喷墨印刷并在450℃时迅速退火，可以直接获得平均透光率为84．14％、方块电阻为202．7Q／口的ITO电极。由喷墨印届4直接制造的ITO电极制备的有机太阳能电池具有0．57V的开路电压、8．47mA／cm^2的短路电流、44％的填充因子以及2．13％的能量转换率。这表明从有机太阳能电池印刷成本效益来讲，相对于溅射工艺，由于无须光刻工艺且ITO材料的利用率更高，直接利用喷墨印刷制备ITO电极成为一种可行的选择。

| Abstract: | We have demonstrated ink-jet printed indium tin oxide （ITO） electrode for cost-efficient organic solar cells （OSCs）. By ink-jetting of crystalline ITO nano-particles and performing a rapid thermal anneal at 450℃, we were able to obtain directly pattemed-lTO electrodes with an average transmittance of 84. 14% and a sheet resistance of 202. 7Ω/square without using a conventional photolithography process. The OSCs fabricated on the directly patterned ITO electrodes by ink-jet printing showed an open circuit voltage of 0. 57V, short circuit current of 8.47 mA/cm^2, fill factor of 44%, and power conversion efficiency of 2. 13%. This indicates that the ITO directly patterned by ink-jet printing is a viable alternative to sputter-grown ITO electrodes for cost-efficient printing of OSCs due to the absence of a photolithography process for patterning and more efficient ITO material usage. |
