Modulating the structure and property of hole‐transporting organicsemiconductors is of paramount importance for high‐efficiency and stableperovskitesolarcells (PSCs). This work reports a low‐cost peri‐xanthenoxanthene based small‐molecule P1, which is prepared at a total yield of 82 % using a three‐step synthetic route from the low‐cost starting material 2‐naphthol. P1 molecules stack in one‐dimensional
