A study is presented on the preparation of (112) oriented CuInSe//2 thin films with a grain size larger than 30 mu m. These thin films have been grown by magnetron RF sputtering on a glass substrate covered by a crystalline thin metallic layer obtained by an original method which is now being patented.

Abstract
A study is presented on the preparation of (112) oriented CuInSe//2 thin films with a grain size larger than 30 mu m. These thin films have been grown by magnetron RF sputtering on a glass substrate covered by a crystalline thin metallic layer obtained by an original method which is now being patented. The CuInSe//2 targets have been prepared by melting the three elements, Cu, In and Se, in a high pressure furnace using B//2 O//3 as an encapsulant. The structural and electrooptical properties of CuInSe//2 films have been found out to depend on several parameters including substrate temperature, sputtering power, substrate bias, target stoichiometry and deposition rate. CuInSe//2 /CdS solar cells were prepared by flash-evaporating CdS on top of RF sputtered CuInSe//2 films. These solar cells have exhibited high photocurrents, close to 40 mA/cm//2 at a 100 mW/cm**2 illumination, and a maximum efficiency close to 4%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
