A π-conjugated small molecule N, N'-bis(naphthalen-1-yl)-N, N'-bis(phenyl)benzidine (NPB) was introduced into poly(9-vinylcarbazole) (PVK) as a hole transport layer (HTL) in inverted perovskite solar cells (PSCs). The NPB doping induces a better perovskite crystal growth, resulting in perovskite with a larger grain size and less defect density. Thus, the V, J and FF of the PSC were all enhanced. Experimental results show that it can be ascribed to the reduction of surface roughness and improved hydrophilicity of the HTL. The effect of NPB on the aggregation of PVK was also discussed. This work demonstrates the great potential of PVK as the HTL of PSCs and provides an attractive alternative for HTL to realize high-efficiency PSCs.
一种π共轭小分子N，N'-双（萘-1-基）-N，N'-双（苯基）联苯胺（NPB）被引入到聚（9-乙烯基咔唑）（PVK）中，作为倒置钙钛矿太阳能电池（PSC）的空穴传输层（HTL）。NPB掺杂诱导了更好的钙钛矿晶体生长，导致钙钛矿具有更大的晶粒尺寸和更低的缺陷密度。因此，PSC的V、J和FF均得到提高。实验结果表明，这可归因于HTL表面粗糙度的降低和亲水性的改善。还讨论了NPB对PVK聚集的影响。这项工作证明了PVK作为PSC的HTL具有巨大潜力，并为实现高效PSC的HTL提供了一种有吸引力的替代方案。
