This study reports two new, simple and cost‐effective hole transporting materials for perovskite solar cells. These novel structures namely N4,N4,N4′″,N4′″‐tetrakis(4‐methoxyphenyl)‐[1,1′:4′,1″:4″,1′″‐quaterphenyl]‐4,4′″‐diamine (TPA‐BP‐TPA), and (E)‐4′,4′″‐(ethene‐1,2‐diyl)bis(N,N‐bis(4‐methoxyphenyl)‐[1″,1′″‐biphenyl]‐4‐amine) (TPA‐BPV‐TPA) are based on linear π‐conjugated linkers and triphenylamine endcappers. These materials possess good solubility and appropriate highest occupied molecular orbital and lowest unoccupied molecular orbital energy levels. Upon testing them as hole transporting materials in perovskite solar cells, in particular, the device with TPA‐BPV‐TPA exhibits a higher power conversion efficiency (PCE) of 16.42%, which is almost equivalent to the PCE using the conventional expensive 2,2′,7,7′‐tetrakis(N,N′‐di‐pmethoxyphenylamino)‐9,9′‐spirbiuorene (SPIRO‐OMeTAD) compound under similar conditions. Additionally, the device stability measured using this newly developed low‐cost compound retains almost 87% of the initial performance after 10 days compared to standard SPIRO‐OMeTAD‐based devices. From this outstanding outcome it is revealed that simple triphenylamine‐based hole‐transporting materials with various kinds of π‐conjugated linkers can pave the way for developing a new generation of simple hole‐transporting materials for low‐cost perovskite solar cells.

用于钙钛矿太阳能电池的低成本替代高性能空穴传输材料及其与常规SPIRO-OMeTAD的比较研究
这项研究报告了两种新型,简单且具有成本效益的钙钛矿太阳能电池空穴传输材料。这些新颖的结构即N 4,N 4,N 4 ''',N 4 '''-四(4-甲氧基苯基)-[1,1':4',1'':4'',1'''-四苯基] -4 ,4'''-二胺(TPA-BP-TPA)和(E)-4',4'''-(乙烯-1,2-二基)bis(N,N-双(4-甲氧基苯基)[[1'',1'''-联苯] -4-胺)(TPA-BPV-TPA)基于线性π-共轭连接基和三苯胺封端剂。这些材料具有良好的溶解性和适当的最高占据分子轨道和最低未占据分子轨道能级。在将它们作为钙钛矿型太阳能电池中的空穴传输材料进行测试后,特别是具有TPA-BPV-TPA的器件表现出16.42%的更高功率转换效率(PCE),这几乎与使用常规昂贵的2,2的PCE相当。 ′,7,7′-四(N,N'-二-对甲氧基苯基氨基)-9,9'-螺碳硼烯(SPIRO-OMeTAD)化合物在类似条件下使用。此外,与基于SPIRO-OMeTAD的标准设备相比,使用这种新开发的低成本化合物所测得的设备稳定性在10天后仍可保持近87%的初始性能。从这一出色的结果可以看出,具有各种π共轭连接基的简单的基于三苯胺的空穴传输材料可以为开发新一代用于低成本钙钛矿太阳能电池的简单的空穴传输材料铺平道路。
