Performance of hole transporting material (HTM) plays a fundamental role in estimating overall efficiency of perovskite solar cell (PSC). Dopant free HTMs with high intrinsic hole mobility and stability have been emerged as a fascinating choice for production of highly efficient and stable PSCs. Here, we report facile synthesis and implementation of a novel tetrathiafulvalene (TTF) derivative as a dopant free HTM for efficient and ambient stable PSC. The PSC based on dopant free TTF HTM shows remarkable photovoltaic efficiency of 15.66% which is one of highest value for any TTF based HTM. Beside efficiency, PSC based on TTF HTM shows only about 16% decline in initial efficiency even after 45 days storage in ambient conditions without any encapsulation which verifies its excellent ambient stability and hydrophobicity. Furthermore, various physical, electrochemical, photovoltaic and optical parameters of TTF HTM are investigated by highly specialized characterization tools. We affirm these results will be helpful for developing novel HTMs for highly efficient and stable PSCs in future.
