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.　©　(2014)　Trans　Tech　Publications,　Switzerland.
