Described are compounds and mixtures that are useful as hole transport layers of photovoltaic devices, such as perovskite solar cells. The compounds and mixtures include non-lithium containing or lithium-free electrolytes, such as imidazolium-based electrolytes, and small-molecule hole transport structures, such as N,N-di-p-methoxy phenyl amine-based structures. The hole transport structures and electrolytes may be covalently bonded or may be separate molecules. The hole transport structures and electrolytes may include cross-linkable groups and may be cross-linked. Devices employing the compounds and mixtures as hole transport layers are also described, such as photovoltaic devices. Synthetic methods of making small-molecule hole transport compounds are also described.
