Abstract
We investigate anisotropic texturing method for crystalline silicon solar cells with sodium carbonate solutions. Texturing temperature have a large effect on the density of pyramid. The dependence of the surface reflectance on solution temperature and the etching time was investigated. The surface morphology was observed by scanning electron microscope and the surface reflectance was evaluated. The reflection from the silicon surface in the wavelength range 400 to 1000nm is reduced to about 12%.
