This issue of Joule features an article by Wang et al. that demonstrates that high-efficiency tin-based solar cells can be realized by the formation of a heterostructure consisting of two-dimensional (2D) and three-dimensional (3D) perovskites based on phenylethylammonium tin iodide (PEA2SnI4) and formamidinium tin iodide (FASnI3), respectively, forming from the study of the PEA2(FA)n-1SnnI3n+1 system. The authors convincingly show that these self-assembled heterostructures can be manipulated and ordered sequentially by chemical means, thus providing a new avenue for further improving the perovskite solar cell technology.
