摘要：
Enhancing hole extraction and transfer of the hole transport layer (HTL) is urgently needed to achieve excellent performance perovskite solar cells. Herein, a novel phthalocyanine (TQ) has been introduced into Spiro-OMeTAD to finely optimize the hole transport properties of the HTL for achieving better performance. It is demonstrated that TQ incorporation can effectively enhance hole extraction/transfer and reduce charge recombination in the device. The TQ-treated device yields an improved power conversion efficiency of 24.29% from 21.91%. Remarkably, these unencapsulated devices demonstrate remarkable moisture, light, and thermal stabilities.
