Kesterite tech news

Hanwha Solutions (KRX: 009830) announced on September 9, 2026, the commercial launch of its "Q.Kore" flexible thin--film series, marking a strategic pivot toward Kesterite (CZTS) technology for the Building--Integrated Photovoltaics (BIPV) sector. The Q.Kore modules utilize a proprietary CZTS formulation deposited on flexible stainless steel substrates using a high--throughput roll--to--roll manufacturing process. Achieving a 19.8% conversion efficiency, the product addresses the critical market gap for lightweight, bendable solar solutions in load--constrained commercial environments. This launch positions Hanwha to capture market share in urban infrastructure projects where traditional, heavy silicon panels are structurally unfeasible.
