Michael Gr?tzel偶爾也跨界做量子點電池，五月他們發表了一篇Advanced Materials文章5，他們通過加入硫氰酸胍進行配體交換，并用溫和的熱退火處理，結果表明， CsPbI3量子點的電荷遷移率和載流子擴散長度顯著提高，量子點電池效率達到15.21%，是當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)，這可以形成一種穩定的D-J混合結構，從而提高穩定性和光電轉化效率。最終他們實現了10.9%的效率，并且連續光照500小時運行良好，文章發表在ACS Energy Letters上7。8one
