Kesterite tech news
Wacker Chemie AG (ETR: WCH) announced on September 14, 2026, the commercial release of its "CrystoKest" high--purity precursor series, a breakthrough in solution--based Kesterite (CZTS) manufacturing.
Key highlights of the release include:
- Atmospheric Deposition: Enables the deposition of absorber layers without high--vacuum equipment, potentially reducing capital expenditure for new production lines by 35%.
- Stoichiometric Precision: Proprietary liquid--phase synthesis minimizes the formation of secondary phases that typically degrade cell efficiency.
- Scalability: The ink--based format is optimized for high--throughput slot--die coating and inkjet printing processes.
Wacker has entered into a joint development agreement to integrate CrystoKest into a 1GW production line, with a formal technical review scheduled for December 2026 and full--scale commercial availability expected by January 2027.
