Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

Reducing non‐radiative charge‐carrier recombination at both p‐ and n‐side interfaces of the perovskite layer is crucial for realizing high‐voltage single‐ and multi‐junction solar cells. Herein, it is demonstrated that co‐depositing a mixture of ethane‐1,2‐diammonium iodide and different oleyl‐based amphiphiles ren...
