Metallophthalocyanines (MPcs) are used as cost-effective and thermally stable hole-transporting materials (HTMs) in the production of perovskite solar cells (PSCs). Unlike the mostly used n-i-p type PSCs, there are a few studies based on p-i-n type PSC with pthalocyanine HTMs. Here, for the first time, both tetra and octa substituted zinc and copper phthalocyanines have been studied as hole transporting materials in the inverted-type (p-i-n) PSCs without using any dopant material. The developed tetra substituted ZnPc and CuPc possess four dichlorophenylthio groups, and the octa-substituted Pcs have eight dichlorophenylthio groups in their peripheral position which enhance their solubility in perovskite-friendly solvent and improved thin film quality. In the inverted solar cell (ITO/HTM/CH₃NH₃Pbl₃/PCBM/Al), methylammonium lead iodide (MAPI) was used as the active layer and [6,6]-phenyl-C61-butyric acid methyl ester (PC₆₁BM) as the electron transport material. Devices based on tetra substituted zinc and copper Pcs, as dopant-free HTMs, indicated significant efficiency enhancement and cell stability compared to similar octa substituted Pcs. While the open-circuit voltage (V_oc) for the reference PEDOT:PSS was measured 0.77 V, for tetra substituted CuPc was found to be 0.83 V. Due to higher V_oc value, tetra substituted CuPc is an appropriate candidate that can replace expensive and unstable HTMs that are currently used in PSCs.

金属酞菁（MPcs）在钙钛矿型太阳能电池（PSC）的生产中用作具有成本效益且热稳定的空穴传输材料（HTM）。与最常用的压区PSC不同，有一些基于销型PSC和邻酞菁HTM的研究。在这里，首次在不使用任何掺杂剂的情况下，对四取代和八取代的锌和铜酞菁进行了研究，将其作为倒型（引脚）PSC中的空穴传输材料。所开发的四取代的ZnPc和CuPc具有四个二氯苯硫基，并且八取代的Pcs在其周边位置具有八个二氯苯硫基，这增强了它们在钙钛矿友好型溶剂中的溶解度并改善了薄膜质量。在倒置太阳能电池（ITO / HTM / CH ₃ NH ₃使用Pbl ₃ / PCBM / Al），甲基碘化铅碘化物（MAPI）作为活性层，使用[6,6]-苯基-C61-丁酸甲酯（PC ₆₁ BM）作为电子传输材料。基于四取代的锌和铜Pcs的设备作为无掺杂的HTM，与相似的八取代的Pcs相比，显示出显着的效率增强和电池稳定性。尽管参考PEDOT：PSS的开路电压（V _oc）为0.77 V，四取代的CuPc的发现为0.83V。由于较高的V _oc值，四取代的CuPc是可以替代昂贵的合适的候选材料和目前在PSC中使用的不稳定的HTM。
