Michael Gr?tzel偶爾也跨界做量子點電池，五月他們發(fā)表了一篇Advanced Materials文章5，他們通過加入硫氰酸胍進(jìn)行配體交換，并用溫和的熱退火處理，結(jié)果表明， CsPbI3量子點的電荷遷移率和載流子擴散長度顯著提高，量子點電池效率達(dá)到15.21%，是當(dāng)時鈣鈦礦量子點電池效率最高值。
7one除了鉛鈣鈦礦，Gr?tzel也開始做錫鈣鈦礦太陽能電池。他們在FASnI3體系中加入大體積二價有機陽離子：4-(氨甲基)-哌啶(4AMP)，這可以形成一種穩(wěn)定的D-J混合結(jié)構(gòu)，從而提高穩(wěn)定性和光電轉(zhuǎn)化效率。最終他們實現(xiàn)了10.9%的效率，并且連續(xù)光照500小時運行良好，文章發(fā)表在ACS Energy Letters上7。8one
