A photo-crosslinkable bis-triarylamine side-chain polymer as a hole-transport material for stable perovskite solar cells

Abstract

A crosslinkable acrylate random copolymer with both bis(triarylamine) and photocrosslinkable cinnamate side chains is compared to the widely used poly(4-butyl-triphenylamine-4′,4′′-diyl) as a hole-transport material in perovskite solar cells.
