喷墨打印制备水溶剂钙钛矿太阳能电池

Inkjet Printing of Perovskite Solar Cells Using Water Solvents

传统硅基太阳能电池的成本居高不下,溶液法制备的大面积、低成本电池是太阳能电池研究和发展的重要方向。喷墨打印制备工艺操作简单、靶向性强、材料利用率高,可大面积沉积钙钛矿薄膜,并且本文使用无毒试剂(水)做溶剂添加表面活性剂调节溶液表面张力,代替先前的有毒试剂,不会腐蚀喷墨打印头,是一种绿色打印技术,在标准光照下(AM1.5,100 m W cm-2)获得了13.2%的光电转化效率。

Due to high cost of conventional silicon-based photovoltaic technology, solution-coating technologies have been explored for the development of large-area and low-cost solar cells. Inkjet printing is a material-conserving deposition technique used for control deposition, enabling easy and fast deposition of functional materials on various substrates with large area. Replacing toxic solvents with nonhazardous solvents, adding surfactant solution to adjust surface tension can not corrosion inkjet print head, it is a kind of green printing technology. With a power conversion efficiency of 13.2 % under standard conditions （AM 1.5, 100 mW cm-2）.
