Interdiffusion of CdS/CdTe in Laser-Deposited and Rf Sputtered Alloys, Bilayers and Solar Cells

Research output: Contribution to conference › Paper

Abstract

We have studied interdiffusion between CdS and CdTe in solar cells, bilayers, and in alloy films by Rutherford backscattering (RBS), Raman scattering, photoluminescence (PL), optical absorption and x-ray diffraction. The cells and films were fabricated by laser physical vapor deposition (LPVD) or by rf sputtering (RFS). We also have prepared films of the ternary alloy material (CdS/sub x/Te/sub1-x/) by LPVD, related film composition to target composition by WDS, and obtained values for band bowing, lattice constant, phonon frequencies, and low temperature PL characteristics. The RBS spectra, obtained from thin bilayers of CdTe/CdS on fused silica, provide information on interdiffusion with~200 .ANG. depth resolution.
