Abstract: The teachings herein pertain to hole transporting compounds containing a cyclobutyl moiety, which can be made into organic hole conductors and into hole transporting material. Additionally, optoelectronic and photoelectrochemical devices comprising such hole transporting material or hole transporting compound are described, in particular photovoltaic devices, organic-inorganic perovskite films, layered photovoltaic devices, p-n heterojunctions, dye-sensitized solar cells, organic solar cells and solid-state solar cells. Notably, a fabricated perovskite solar cell module using a disclosed HTM compound exhibited a record efficiency over 19.0% with an active area of 30.24 cm2.

Abstract: The 9,9′-spirobifluorene-based compounds and mixtures including 9,9′-spirobifluorene compounds with crosslinkable functional groups and compounds with two or more thiol groups, can stabilize one or more underlying layers of the hole transporting layer and/or interlayer during liquid fabrication process of optoelectronic and/or photoelectrochemical devices. More particularly, the compounds are hole transport materials that include crosslinkable functional groups covalently bonded to 9,9′-spirobifluorene hole transporting structure and mixtures including hole transporting crosslinkable 9,9′-spirobifluorene and thiol derivatives, which may crosslink, such as by exposure to UV, visible light, and/or heat. Photovoltaic devices may employ these compounds and mixtures in crosslinked forms.
