In this study, the viability of growing a CuInSe 2 thin film solar absorber by sputtering using a single target composed of CuSe and InSe powders was investigated. It was found that the ability to obtain a sputtered film with a stoichiometric composition was greatly dependent on the substrate temperature and that the optimum conditions could be obtained by adjusting the sputtering radio. RF sputtering: A viable tool for MEMS fabrication obtain highly c-axis oriented ﬁlms, which is a requirement for these ﬁlms to be piezoelectric in nature. In addition to the dielectric ﬁlms, thin ﬁlms of Cr, Au, Ti and Pt on silicon or glass substrates, (used for ZnO deposition) were also deposited by RF sputtering process.
CuInS 2 thin films were deposited by chemical spray pyrolysis from aqueous solutions containing CuCl 2, InCl. and thiourea at substrate temperature of °C and annealed at °C in air. [Cu]/[In] molar ratio was varied from to in precursor solution. The influence of [Cu]/[In] molar ratio on structural, morphological and optical properties of CuInS2 thin films was Author: Mazabalo Baneto, Damgou Mani Kongnine, Krishnasamy Ravichandran, Donafolgo Soro, Koffi Sagna, Kossi.

Summary. Electrical data from sputtered and annealedp-type CuInS 2 thin films have been obtained over a range of temperatures. An analysis of hole mobilityvs. temperature data indicates that the charge carriers are predominantly scattered by neutral and ionized impurities and by acoustic-mode by: 3.
The results showed that the pure, flatness, and well crystallized CuInS2 thin films with good electrical and optical property had been obtained, meaning that the chemical bath deposition in acid. CuInS2 thin films were fabricated by one-step electrochemical deposition from a single alkaline aqueous solution and using conductive glass as the substrate.
This chapter describes fabrication and characterization CuInS2 based solar cell with Cd-free I3-In2S3 buffer layer using CSP technique. This technique is quite suitable for solar cell production because of the possibility of large area deposition of thin films at low.
A segmented Zn:Al-target with an Al-content of wt% was used. The oxygen flow during sputtering was in the range of – sccm (standard cubic centimeter per minute).
The layer thicknesses ranged from to nm. Subsequently, CIS films were deposited by RF reactive sputtering with a conventional RF ( MHz) sputter by: 6. In general, the wide range of alloy compositions investigated and the associated properties of the CuInSe 2 films obtained has provided useful information necessary for further optimization of the process steps of the co-sputtering and the graphite box selenization techniques for the fabrication of quality CuInSe 2 thin by: Thin film deposition.
