METHOD FOR MANUFACTURING n-p-p STRUCTURE SOLAR CELL Russian patent published in 1999 - IPC

FIELD: optoelectronic devices including solar cells. SUBSTANCE: manufacture of solar elements using n⁺-p-p⁺ structure includes following stages: (1) boron and phosphor are simultaneously diffused, respectively, from borosilicate and phosphosilicate films applied to rear and face surfaces; (2) oxide films are chemically removed from both sides of substrate; (3) solar cell face is textured; (4) n⁺ layer is formed; (5) current-collecting contacts are formed. In the process, solar cells of 16.6% efficiency possessing two-sided sensitivity are produced. EFFECT: reduced labor consumption and improved efficiency of solar cells. 2 cl, 1 dwg
