Michael Grätzel偶尔也跨界做量子点电池,五月他们发表了一篇Advanced Materials文章5,他们通过加入硫氰酸胍进行配体交换,并用温和的热退火处理,结果表明, CsPbI3量子点的电荷迁移率和载流子扩散长度显著提高,量子点电池效率达到15.21%,是当时钙钛矿量子点电池效率最高值。
7one除了铅钙钛矿,Grätzel也开始做锡钙钛矿太阳能电池。他们在FASnI3体系中加入大体积二价有机阳离子:4-(氨甲基)-哌啶(4AMP),这可以形成一种稳定的D-J混合结构,从而提高稳定性和光电转化效率。最终他们实现了10.9%的效率,并且连续光照500小时运行良好,文章发表在ACS Energy Letters上7。8one
