ABSTRACT:
Semiconductors are textured with aqueous solutions containing non-volatile alkoxylated glycols, their ethers and ether acetate derivatives having molecular weights of 170 or greater and flash points of 75° C. or greater. The textured semiconductors can be used in the manufacture of photovoltaic devices.
