Halide perovskites are of recent interest for photovoltaics. With roughly 1664 potential “simple” halide perovskites alone, how does one reasonably reduce the search space to identify those that form without excessively investigating those that won’t form? Currently, less than 16% of the 1664 potential simple halide perovskites are reported to form. Researchers continue to primarily utilize Goldschmidt’s tolerance factor formalism (GTFF), a nearly 100-year-old correlation relation, to investigate formation of perovskites. Here, the utility of the “new simple material model” (NSMM) is shown to be on par with GTFF for identifying roughly 90% of the simple halide perovskites that form; yet, NSMM outperforms GTFF, about 70% to 10%, respectively, for identifying potential simple halide perovskites that don’t form. Hence, the advantage of NSMM to rapidly and significantly reduce the field of search of novel simple halide perovskites is demonstrated. Additional benefits of NSMM are also discussed. |
