Application

Tin iodide finds application in synthesis of perovskites based photovoltaic materials. Our perovskite grade SnI2 can readily be dissolved in DMF to yield 1M solution.
Tin(II) iodide can serve as a starting material or precursor for tin-based perovskite absorber layers in perovskite solar cells. Tin(II) iodide perovskite-based structures can be employed in sensitizers, photodetectors, and sensors due to their tunable bandgap, high absorption coefficient, and efficient charge carrier transport. These properties make them suitable for applications in light sensing and detection. Tin(II) iodide perovskite structures show promise as materials for energy harvesting and conversion.

Solar Cells: Towards Printable and Flexible Solar Technologies

To achieve net-zero emissions by 2050, renewable power contributions must triple. Photovoltaic stations provide vital utility power, achieved primarily through third- and fourth-generation technology. Promising trends include recycling and revolutionary, ultra-lightweight, flexible, and printable solar cells.
