New Success Story: KESPER
The M-ERA.NET KESPER project ventured into developing multinary kesterite compound for photoelectrochemical water splitting and ammonia generation.
Despite relentless efforts to improve, the instability of kesterite in aqueous media and control over phase impurities posed a setback to achieve the ambitious objectives of the project. Not deterred by the setback, the project continued to improve material quality and look for alternative promising absorber systems. While doing so, a unique wide band gap chalcogenide absorber based Cu(In,Ga)S2 was developed that was not only stable in aqueous media but also facilitated water splitting, nitrate reduction, and CO2 redcution, without any protection layer or using a co-catalyst.
