| Cadmium sulfide (CdS) is widely used in photovoltaic cells as the best-suited window material for CdTe and CuIn(Ga)Se2 due to its optical and structure properties. However, its electrical properties are very far from the optimum. The composition plays an important role in both optical and electrical properties, in order that the best optical property can be found in compositions close to stoichiometry (Cd 50at S 50% at) and the best electrical properties are found in compositions of CdS 60% at 40% at. In this work we present an optimization of CdS thin film as a window layer. The thin film is a composite of a CdS matrix containing CdS nano-particles with different composition. The composition of the matrix allowed the best electrical properties and the composition of the nano-particles allowed the best optical properties. The optimized CdS thin film was deposited by microwave assisted chemical bath process (MA-CBD). Chemical solution used for the deposition is comprised of Cadmium Nitrate (Cd(NO3)2), Sodium Citrate (Na3C6H5O7), Thiourea (CS(NH2)2) and Ammonium Hydroxide (NH4OH). Composition of the films was analyzed using energy dispersive x-ray spectroscopy (EDS). Optical transmittances of the films have been determined by spectrophotometer over the wavelength range of 300-1100 nm. The electrical resistivity of the CdS films was measured at room temperature using the four-probe technique | |
