Perovskite solar cells adopting a layer of various nanocrystals (NCs) on top of perovskite film exhibit similar enhancement of the photovoltaic (PV) properties regardless of the kind of NC material, even though NC materials possess different electrical and optical properties. In this paper, we reveal that the key reason for the enhanced PV performance is the surface passivation effect of the perovskite film by oleylamine ligands of NCs.

钙钛矿型太阳能电池中配体封端的纳米晶体的再研究作用。

钙钛矿太阳能电池在钙钛矿薄膜上采用各种纳米晶体（NC）层，无论NC材料的种类如何，其光伏（PV）性能都有相似的提高，即使NC材料具有不同的电学和光学特性。在本文中，我们揭示了提高PV性能的主要原因是NCs的油胺基配体对钙钛矿薄膜的表面钝化作用。
