Abstract

(112) oriented CuInSe2 thin films with grain size larger than 30 microns have been grown by magnetron RF sputtering on a glass substrate covered by a crystalline thin metalic layer obtained by a novel method. The CuInSe2 targets have been prepared by melting Cu, In, and Se in a high-pressure furnace using B2O3 as an encapsulant. The structural and electro-optical properties of CuInSe2 films have been found to depend on substrate temperature, sputtering power, substrate bias, target stoichiometry, and deposition rate. CuInSe2/CdS solar cells prepared by flash-evaporating CdS on top of RF-sputtered CuInSe2 films have so far exhibited high photocurrents, close to 40 mA/cm2 at 100-mW/cm2 illumination, and a maximum efficiency close to 4 percent.
