科研方向
_________________________________________________________________________________________

2013年兴起的钙钛矿太阳能电池具有光电转换效率高(22.1%)、制备成本低(仅为传统硅电池的1/5~1/10)的优点。柔性化将进一步推动其应用进程。本小组致力于采用新型柔性透光导电材料为基底,制备柔性高效高稳定性的钙钛矿太阳能电池。相关研究方向如下:

1. 柔性钙钛矿太阳能电池:致力于太阳电池的低成本、柔性化与高稳定性,探讨器件光电转换物理机制;目前,课题组采用高导电碳膜做顶电极,成功制备出效率大13%,非封装器件在70%-90%的高湿度环境下稳定时间达到1000h,相关成果已发表。课题组计划基于此,拟开展基于丝网印刷技术的柔性、大面积、模块化钙钛矿太阳能电池制备与研究。

2. 柔性透明电极:ITO等导电玻璃柔性差,为此课题组采用具有优异抗弯曲性能的银纳米线制备柔性透明电极;目前,课题组已制备出透过率90%,方阻10ohm的高透光导电电极,部分成果已申请专利或以论文形式发表。

3. 无序网格拓扑与导电行为:结合图论理论,深入理解无序网络中团簇的产生、发育以及融合过程,并理解其对网络导电行为的影响机制。

以上研究中,研究内容2、3是研究内容1的基础,三者之间有机联系,最终服务于高效性、高稳定性的柔性钙钛矿太阳能电池。
