Optimum Process of Texturing on Silicon Solar Cell

Abstract:

Silicon solar cell surface texture is effective to reduce reflectance and improve light collection. Alkaline etchants is a conventional process of monocrystalline silicon texturing. Isopropyl alcohol (IPA) as buffer solution is expensive and high consumption, which increased the cost of solar cell. In reserch, It has been found that a cheaper surfactant as buffer solution decrease silicon surface interfacial force and increase etchant infiltrating of silicon wafer, so a large number of small and uniform texture appeared on the silicon surface. Pyramids size of about 3μm formed after etching of 15min. A new process to reduce the production cost and form the high quality pyramids texturing has been developed by the investigation.
