Concentrator PV modules of "all-glass" design with modified structure

A modified structure of the high concentration "all-glass" PV modules with III-V solar cells is presented. In the "all-glass" module design, the secondary small aperture smooth surface lenses arranged in an intermediate composite (glass-silicone) panel are inserted between a panel of the primary composite Fresnel lens concentrators (each of 40 /spl times/ 40 mm/sup 2/) and a panel of the solar cells. Such a design allows fabricating the modules of large total area (up to 0.5 /spl times/ 1 m/sup 2/) and improving environmental protection of the cells. The cells as small as 1.2 mm in designated area diameter operating at very high concentration ratio (more than 1000x) can be used in the developed PV modules.
