Replacement of commonly gold (Au) with other non-precious metals is a crucial step for low-cost perovskite solar cells (PSCs). However, severe performance degradations always occurred when we get rid of the Au electrode, mainly because of the deteriorated hole-transporting properties. Here, we repor...
