为了开发新型的太阳能电池关键材料,合成了一种新的基于咔唑的小分子材料Cz-3Th,将其用作空穴传输材料（HTM）成功地应用到钙钛矿太阳能电池当中。这种新型的小分子材料两步反应即可合成,原料易得且成本较低。在使用低温溶液处理的Sn O2纳米颗粒作为电子传输层的CH3NH3Pb I3钙钛矿太阳能电池中,以Cz-3Th为空穴传输层,在100 m W/cm2AM 1.5 G光照条件下获得0.75 V的开路电压（Voc）,光电转化效率（PCE）为2.68%。因此,在未来趋势为环境友好和低成本效益的钙钛矿太阳能电池中Cz-3Th有很大发展潜力。

英文摘要：

A novel carbazole-based molecule Cz-3Th was synthesized and successfully applied as hole- transporting material （HTM） of CH3NH3PbI3-based perovskite solar cells. The investigated hole- transporting material was synthesized in two steps from commercially available and relatively inexpensive starting reagents. The Cz-3Th was exploited in lead halide planar perovskite solar cells using low- temperature solution-processed SnO2 as the electron transporting layers, delivering a power conversion efficiency（PCE） of 2.68% with an open-circuit voltage（ Voc） of 0.75 V under 100 mW/cm2 AM 1.5 G solar illumination. These promising results highlight the potential application of the Cz-3Th in the cost- effective and environment-friendly perovskite solar cells.
