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202.7Ω/□的ITO电极。由喷墨印刷直接制造的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。
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.
