Abstract
In this work, the influence of the annealing temperature on the optical properties of the thin films Cadmium Sulphide (CdS) has been studied. Thin films of Cadmium Sulphide (CdS) were made using the Physical Vapor Deposition (PVD) method. The optical properties of annealing temperatures (as deposited, 200, 250, and 300 ) were scrupulous. The UV/VIS spectrophotometer investigated optical parameters such as transmission, the coefficient of absorption and energy gap of the films for the range (400-110 nm) as an assignment of the annealing temperature. The optical properties were calculated as a function of annealed temperature: absorption, transmission, reflection, band gap, coefficient of absorption, excitation coefficient and index of refraction.

The semiconductor manufacturing products spread throughout the world and penetrate pointedly into the daily life of an epidermal existence
Cadmium Sulphide (CdS) thin film development was based on organic metal vapor deposition (MOCVD), spray pyrolysis deposition (SPD), close-spaced sublimation (CSS), successive ionic layer adsorption and reaction (SILAR) and chemical bath deposition (CBD) [8]
The optical properties of Physical vapor deposition (PVD) CdS thin films are based on the parameters of proportional reactant condensation for chemical reaction, films thickness, aqueous solution PH and annealing temperature
Summary
The semiconductor manufacturing products spread throughout the world and penetrate pointedly into the daily life of an epidermal existence. Thin films are well known as stamping for enforcement in abundant physically established profession [1]. Interest in the physical properties of thin films has increased significantly in recent years as new effects may appear in film statements that are not observed in bulk samples [2]. Cadmium sulfide thin film is a suitable n-type semiconductor for an opening layer in solar cells for CdTe/CdS heterojunction [3,4]. Physical vapor deposition (PVD) has become an engaging technique due to its naivety, low cost and look high accuracy data technology, with a large surface and large surface deposition at low temperatures [9]. The purpose of this work the effect of annealing on CdS thin film optical parameters
