Physical and chemical properties of dust in the Pre-Aral region of Uzbekistan

particles to stay there for longer time. Although the measure-
ment shows particle size is of few hundreds of nanometers 
that can be of wire type particle that can enter the nanometer 
scale wall of the texturized glass. If that is the case, it will 
be difficult to remove such particles from the glass surface. 
Upon long time exposition of such texturized glass without 
cleaning or after dust storm, the nanosize voids of texture 
can fill out with smaller size dust particles that might drasti-
cally reduce the PV module efficiency.
