How about monocrystalline silicon solar cell?

Among the silicon solar cells, monocrystalline silicon solar cells have the highest conversion efficiency and the most mature technology. High-performance monocrystalline silicon cells are based on high-quality monocrystalline silicon materials and related thermal processing techniques. The cell technology of monocrystalline silicon is almost mature. In cell production, surface texturing, emitter passivation, zone doping and other technologies are generally used. The developed cells mainly include planar monocrystalline silicon cells and grooved buried gate electrodes monocrystalline silicon battery. The improvement of the conversion efficiency mainly depends on the surface microstructure treatment of single crystal silicon and the zone doping process.
