Description:For normally incident light falling upon periodic textures, angles of 45° ensure double-bounce reflectances will occur; angles of 60° yield triple-bounce reflectances at least. As facet tilt angles decrease below a , 45°, less and less light will receive double-bounce incidence, closer to the base of the grooves, until at angles below 30°, no light will receive multiple bounce incidence in air, and reflectance levels are equivalent to that of polished silicon

description:here,the substrate is etched with HCL solution and in the DC and RF sputtering on glass substrates from ceramic (ZnO:(Al)2(O)3 and metallic (Zn:Al) targets respectively,then it is compared with electro-opto properties of smooth ZnO substrate.

result:by this,separate optimization of the electro-optical and light scattering properties was done.resistivity decreased,reflection loss decreased,and transmitting capacity increased
