Description

General description

Tin (II) iodide is widely used as a precursor toprepare lead-free non-toxic hybrid perovskite materials. Tin-based perovskitesshow excellent electrical and optical properties such as high charge carrier mobility,absorption coefficient, and small exciton binding energies.

Application

Tin(ll) iodide can be used as a starting material to prepare an efficient hybrid perovskite solar cell (HPSC). The addition of a small amount of 2D tin film induces well-defined orientation and superior crystallinity in formamidinium tin iodide (FASnI₃) films. This results in the longer life of charge carriers and improves the performance of HPSCs.

It can also be used to preparesolution-processable lamellar hybrid [CH₃(CH₂)₁₁NH₃]SnI₃semiconductor.
