Sprayed SnO/sub 2/ antireflection coating on textured silicon surface for solar cell applications

This paper reports the use of SnO/sub 2/ antireflection coatings deposited through direct liquid spraying of an aqueous solution of SnCl/sub 4/ on randomly upward pyramid textured (100)-Si solar cells. In spite of the adverse characteristic of the process used, the pyramid-like texture was preserved after the film deposition. The hemispherical reflectance of the sprayed-SnO/sub 2//textured-Si structure was comparable to those obtained using conventional techniques.
