Reactive Dissolution of Metals and Metal Compounds with Solutions Containing Polyselenide Ions

Researchers at Purdue University have developed an alternative method to form selenide films by the direct dissolution metal-chalcogenide in an amine-thiol solvent system. This approach eliminates the need for hydrazine, a toxic and dangerous material, and allows the use of a safer alternative that produces a high-quality film. This technology is useful for those who want to solution processed metal selenides into films for electronic applications, including solar cells.

Advantages:

- Direct dissolution of metals and metal compounds

- Solution processing yielding high quality films

- Elimination of hydrazine

Applications:

- Solution processing of selenide films

- Electronics and solar cell applications

Technology Validation:

This technology has been validated through laboratory testing.
