Article Preview

Silicon solar cell surface texture was effective to reduce reflectance and improve light collection. Alkaline etchants was a conventional process in monocrystalline silicon texturing.However, isopropyl alcohol(IPA) as buffer solution was expensive and high consumption, which increased the cost of solar cell. In the paper, 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 very 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 texturization has been developed by this investigation.
