An easily prepared, cost-effective and solution processable tetraphenoxy substituted phosphorous triazatetrabenzo corrole (P^VTBC) was synthesized and tested as the hole transporting material (HTM) for MAPbI₃ perovskite solar cells (PSC). This phthalocyanine analogue HTM works efficiently in the absence of any dopant or additive for the device composed of FTO/c-TiO₂/m-TiO₂/MAPbI₃/HTM/Au. The optimized undoped mesoscopic solar cell device based on the P^VTBC compound exhibited a good power conversion efficiency (PCE) of 16.1% (measured at 100 mW cm² illumination, AM 1.5G), together with a good long-term stability under ambient conditions, in contrast to the PCE of 11.2% for Spiro-OMeTAD under the same condition. This result paves the way for further developing TBC as a new type of low cost HTMs.

合成了一种易于制备，具有成本效益且可溶液加工的四苯氧基取代的三氮杂三苯甲酸磷酯（P ^V TBC），并作为MAPbI ₃钙钛矿太阳能电池（PSC）的空穴传输材料（HTM）进行了测试。对于由FTO / c-TiO ₂ / m-TiO ₂ / MAPbI ₃ / HTM / Au组成的设备，该酞菁类似物HTM在不存在任何掺杂剂或添加剂的情况下都能有效工作。基于P ^V TBC化合物的优化的无掺杂介观太阳能电池器件表现出16.1％的良好功率转换效率（PCE）（在100 mW cm ^2下测量）Spiro-OMeTAD的PCE为11.2％，而在相同条件下的PCE为11.2％。这一结果为进一步开发TBC作为一种新型的低成本HTM铺平了道路。
