Abstract

Organic hole transport material (HTMs) is one of the important components in perovskite solar cell (PSC) to improve the device performance and device stability. Most of the reported HTMs require p-type dopants to improve the conductive of the hole transport layer and further improve the power conversion efficiency (PCE). However, the dopants added into the HTM layers have been confirmed that are moisture sensitive, which may accelerate the degradation of the solar cell devices and induce device instable. In this work, we designed a new series dopants-free HTMs named X61 and X62 with spiro[dibenzo[c,h]xanthene-7,9'-fluorene] (SFBX) as the skeleton. We plan to calculate their conductivity and hole mobility, as well as HOMO/LUMO energy levels.
