Amphiphilic hole-transporting materials minimize the buried interfacial defects for efficient p-i-n perovskite solar cells

<正>The explosive growth of academic research on perovskite solar cells(pero-SCs) was initiated by a key innovation that incorporated solid-state hole-transporting materials(HTMs)to replace the liquid electrolyte used in the early studies of pero-SCs [1].Since then,tremendous efforts have been devoted to the development of new HTMs,aiming to further enhance the photovoltaic performance and stability while decreasing the cost of the HTMs [2–5].
