In article number 1700265 , Annalisa Bruno and co‐workers show that applying an electrical poling to precondition the SCs below 170 K, the MA + cations can be efficiently oriented and I − accumulation at the TiO 2 /MAPbI 3 interface is facilitated. Both phenomena lead to improved charge transfer efficiency at the interface. In the cover, the MAPbI 3 and TiO 2 interface in a solar cell at low temperature under electrical poling is highlighted.
