Introduction Because of their advantage as flame retardants and smoke suppressants, zinc hydroxystannate (, ZHS) and zinc stannate (, ZS), have found commercial use for many polymeric materials, including plastics and rubbers [1-3], especially for halogen-containing polymers, such as poly(vinyl chloride)[4,5].
Experimental Materials.
Heat release rate (HRR) and smoke parameters such as total carbon monoxide production and total carbon dioxide production are important parameters for evaluating flame retardancy and flammability of polymeric materials.

Introduction Solar cell for silicon based material is the most widely used technology for the manufacture of photovoltaic modules due to the low cost.
In the former approach, the solar cells are fabricated using materials with specifically chosen energy gap characteristics designed to absorb photons of different wavelengths so as to reduce the energy loss in the carrier energy gap zone.
A III-V GaAs/AlGaAs solar cell materials with  surface selective etching and polymer passivation, the incident light reflected from the solar cell is re-directed by a reflective diffraction optical grating such that it is refocused on the barrier-type surface of the solar cell.
