Abstract

Perovskite solar cells have attracted enormous attentions due to its high efficiency and low cost. Hole transport materials, as one of key components in the related device, play a crucial role in facilitating charge transportation and collection. However, even the state-of-the-art hole transport materials, such as Spiro-OMeTAD and PTAA, duffer from some disadvantages of low conductivity ans hole mobility. Therefore the dopants are necessary during their application. These dopants are either volitile or hygrogrotic, which eventually affect the device stability. To address this issue, Hereby, we we develop 3 polymeric materials, which could be facilely synthesized and cost effective. By ultilizing these polymeric materials, we achieved an unprecendent efficiency of 20.2%, which is also one of the best results achieved for dopant free HTMs based PSCs. However, to get further insight into the molecular configuration and frontier electron distribution, we require the aids from the calculating simulation.
