摘要：

To abate the issue of moisture-assisted phase transition of CsPbI2Br, caused by hygroscopic dopants used in the hole-transporting material (HTM), developing dopant-free HTMs is necessary. In this work, a new polymer, PDTDT, is developed as a dopant-free HTM for CsPbI2Br solar cells, and the device performance and stability are systematically compared with cells employing dopant-free P3HT. CsPbI2Br solar cells using PDTDT show an efficiency of 17.36% with V-OC of 1.42 V and FF of 81.29%, which is one of the highest values for CsPbI2Br cells. Moreover, a record-high efficiency of 34.20% with V-OC of 1.14 V under 200 lux indoor light illumination and efficiency of 14.54% (certified efficiency of 13.86%) for a 1 cm(2) device under one sun are accomplished. Importantly, PDTDT shows superior/comparable device stability to P3HT, promising its potential to be an alternative to popular doped Spiro-OMeTAD and P3HT HTM.
