C-60 Thin Films in Perovskite Solar Cells: Efficient or Limiting Charge Transport Layer?

Mohammad Khaja Nazeeruddin, Cristina Roldán Carmona, Hiroyuki Kanda, Albertus Adrian Sutanto, Cansu Igci, Nadja Isabelle Desiree Klipfel, Maria Cristina Momblona Rincón

In this work, we identify the importance of C-60 and compact-TiO2 (cTiO(2)) as electron transport layers on the device performance of coevaporated n-i-p perovskite solar cells. We found (1) a synergetic effect between both layers when extracting the charge ...
