Guanidinium Iodide (GAI), >=99.5%

Cat No:BMSPEM-0091

Description

Guanidinium iodide (GAI) belongs to the polar symmetric guanidinium salt family. Iodide and bromide salts of alkylated halides are used to produce perovskites for solar photovoltaic panels; as a passivation material, GAI strengthens grain boundaries and raises open-circuit voltage in perovskite absorbers, and it is further applied in the fabrication of perovskite solar cells. The compound is furnished at >=99.5% purity after four purification passes.
