Here, we report a new alternating conjugated polymer containing two building blocks based on B-N unit. The polymer exhibits strong light absorption in the visible range, low-lying LUMO/HOMO energy levels and moderate electron mobility. The resulting all-PSC devices exhibit power conversion efficiencies of 1.50%-2.47%.展开更多
