Cross-linkable carbazole-based hole transporting materials for perovskite solar cells

Carbazole-based molecules V1205 and V1206 capable of cross-linking via three vinyl groups were synthesized by a simple process and applied as hole-transporting materials (HTMs) in inverted perovskite solar cells (PSC). Novel HTMs were thermally polymerized to provide films resistant to organic solvents. A PSC with V1205 exhibited a photovoltaic conversion efficiency of 16.9% with good stability.
