Cell efficiencies of higher than 18% using quasi-mono wafers have been claimed by Taiwan-based cell producer, Gintech Energy. To be displayed at PV EXPO 2012 in Japan in March, Gintech also said its optimized pattern design and process recipe has achieved cell efficiencies of 19% for its Douro Series monocrystalline solar cells and more than17% for its multicrystalline solar cells.
The quasi-mono-based solar cells will be sold under its Solar Hybrid brand and employ a front alkaline textured surface with SiNx anti-reflecting coating with a back aluminium surface field. The cells can be used in modules to develop 255W/300W modules made of 60/72 cells.
