Tin Halides (93)

Tin halides, such as tin diiodide and tin tetraiodide, possess narrow band gaps and optoelectronic characteristics similar to lead-based counterparts, making them promising materials for perovskite solar cells. Their non-toxic nature adds to their suitability for practical use. These attributes enable tin halides to serve as absorber layers in perovskite solar cells, offering a potential solution to the toxicity concerns of lead-based compounds while maintaining excellent photoelectric conversion efficiency.
