摘要
近年来,新型活性层材料的发展和对活性层形貌的精确调控极大地促进了有机光伏电池(OPV)的发展,在实验室制备的小面积OPV的能量转换效率(PCE)已经超过19%.然而,面向未来商业化应用的高效且稳定的大面积OPV模组的制备仍然面临诸多挑战,因此相关研究受到广泛关注.本文采用低成本的红外纳秒激光器刻蚀和图案化制备了大面积OPV模组,与通常采用飞秒激光器进行烧蚀相比,该方法可大幅降低设备和维护成本;研究和优化了各功能层的激光加工参数,降低了对ITO透明电极的损伤;利用底层ITO的热效应实现了对红外光吸收较弱的中间有机层的烧蚀;最后,制备了有效面积为28 cm^(2),几何填充因子(GFF)超过93%的OPV模组,能量转换效率达到14.33%.本工作研究了利用低成本纳秒激光器辅助制备高GFF大面积OPV模组的方法,有利于促进大面积OPV模组的研究和产业化应用.
The development of new active layer materials and the precise regulation of active layer morphologies have greatly facilitated the advances of organic photovoltaic cells(OPVs)and have recently enabled the power conversion efficiency(PCE)of small-area OPVs to exceed 19%in the laboratory.However,the preparation of efficient and stable large-area OPV modules still faces challenges for its industrialization in the future and draws great attention in recent years.Herein,high-performance large-area OPV modules were fabricated by using an infrared nanosecond laser to achieve accurate ablation and patterning of the individual functional layers.Compared to the commonly used femtosecond lasers for the fabrication of OPV modules,infrared nanosecond laser-assisted preparation of OPV modules is promising to reduce the manufacturing cost.The laser processing for the ablation of the individual layers was investigated and the damage to indium tin oxide(ITO)transparent electrode was effectively reduced by precise adjustment of laser parameters.The ablation of intermediate organic layers with weak infrared absorption was realized with the help of thermal effect coming from the under ITO layer.The large-area OPV module with an effective area of 28 cm^(2) and a high geometric fill factor of more than 93%was fabricated and an overall PCE of 14.33%was achieved.The demonstrated preparation of large-area high-performance OPV module via ablation of infrared nanosecond laser holds potential to advance the development of large-area OPV devices and paves the way for its commercialization in the future.
