The present invention provides novel triazatruxene derivatives that are useful as hole transport materials (HTM), particularly, in optoelectronic devices. The utility of the novel compounds was confirmed in solid-state, sensitized solar cells based on organic-inorganic perovskites used as light harvesters. The devices achieved high power conversion efficiencies.

A process of forming a thin film photoactive layer of an optoelectronic device comprising: providing a substrate having a surface comprising or coated with a metal M selected from at least one of Pb, Sn, Ge, Si, Ti, Bi, or In; and converting the metal surface or metal coating of the substrate to a perovskite layer.

Hybrid organic-inorganic perovskite thin films with average grain sizes of at least 50 micrometers were prepared and employed in solar cells. The PCE values of the solar cells did not degrade with the direction or the scan-rate of the applied voltage. The larger average grain sizes are believed to assist in reducing the influence of defect states on carrier recombination. The tunability of PCE with substrate temperature may be correlated to the quality of the crystalline perovskite formed using the hot-casting procedure. The larger average grain sizes lead to good crystalline quality, low defect density, and high carrier mobility. The process for growing hybrid organic-inorganic perovskites may be applicable to the preparation of other materials to overcome problems related to polydispersity, defect formation, and grain boundary recombination.
