The Thermomechanical Properties of Thermally Evaporated Bismuth Triiodide Thin Films.

Bismuth triiodide (BiI) has been studied in recent years with the aim of developing lead-free semiconductors for photovoltaics. It has also appeared in X-ray detectors due to the high density of the Bismuth element. This material is attractive as an active layer in solar cells, or may be feasible for conversion into perovskite-like material (MABiI), being also suitable for photovoltaic applications.
