Solar-Tectic has recently been granted a patent titled "Tin Perovskite/Silicon Thin-Film Tandem Solar Cell" as part of a "Tandem Series" of high efficiency and cost effective solar cells by Solar-Tectic, with the potential to surpass the efficiencies of thin-film solar cell technologies such as CdTe, CIGS, and a-Si and replace the current silicon technology.

The patent is reportedly the first for a perovskite layer on crystalline silicon thin-film (tandem), and covers all non-toxic perovskites and inorganic materials.
