Abstract
We report on the epitaxial growth of Cu(In,Ga)Se2 (CIGS) thin films on n-type Ge substrates using the Pulsed Electron Deposition (PED) technique. Single-crystal films with smooth interface and no dislocations were obtained at a substrate temperature of 300 °C with thickness above 1.5μm. CIGS/Ge epilayers were characterized in terms of Transmission Electron Microscopy, X-Ray Diffraction and Photoluminescence. Preliminary results are very promising for a variety of potential applications as absorber layer in single and multi-junction thin-film solar cells. © 2014 AEIT.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
