Bismuth(III) halide perovskites are promising alternative absorber materials to commonly used organolead- and organotin-based perovskites due to the low toxicity and ambient stability. In this work, hybrid organic-inorganic bismuth(III) halide perovskites based on methylammonium (CH3NH3+, MA+) as A-site cation and halide counter ions (I-, Cl-) incorporated on the X-site of the perovskite structure were investigated using bismuth(III) halides (BiI3, BiCl3) and methylammonium iodide (MAI) as starting compounds. The perovskite absorber materials (MA3Bi2I9, MA3Bi2I9-xClx) were prepared in a low-temperature solution-based processing route following a one-step and two-step procedure.[2,3] The absorber materials were evaluated with regard to their photovoltaic performance in organic (PEDOT:PSS) as well as in planar (c-TiO2) and meso-structured (c-TiO2/mp-TiO2) perovskite solar cell architecture (Fig. 1). In addition, the perovskites were characterized optically (UV/VIS spectroscopy, light microscopy), structurally (X-ray diffraction), and morphologically (atomic force microscopy).
