Low cost CBD ZnS antireflection coating on large area commercial mono-crystalline silicon solar cells

Abstract Zinc sulfide is a wide band gap semiconductor with high refractive index and hence a promising material for antireflection coating over commercial silicon solar cells. In the present work, attempts have been made to improve the rate of deposition, uniformity of deposited film, stoichiometry, refractive index and the percentage of reflection, respectively, by proper optimization of molar percentage of different CBD ZnS bath chemical constituents and deposition conditions. High values of the rate of film deposition (19.6 A), film uniformity (S.D. 103 mm ×103  mm) mono-crystalline silicon solar cells with CBD ZnS antireflection coating.
