Spiro-OMeTAD as hole transporting material (HTM) has been widely employed up to PCE = 22.1 %, but it is only processed in chlorinated or harmful solvents such as chlorobenzene (CB), dichlorobenzene (DCB), or toluene, despite of its low molecular weight relative to polymeric HTMs. Therefore, it is necessity to replace it to green solvent processable HTM. Here, we report a green solvent processable, polymeric HTM. We design a novel D (e-donor) – A (e-acceptor) type conducting polymer to obtain its proper highest occupied energy level (HOMO) easily and to achieve its high hole mobility. In this talk, I will present a design strategy for a green solvent processable HTM and why it exhibits a highly stable device with a highest PCE. |
