Sets of a solar cell and a lens are obtained on a surface of a solar concentrator module. The solar cell is located at a focal point of the lens. The other sets whose solar cells are replaced with lighting devices are obtained on the opposite surface of the solar concentrator module. Each later set is reversely piled up on a former set. Hence, a light shining through the later set and the former set from the lighting device is focused on the solar cell. Consequently, photoelectric characteristics of the solar concentrator module is tested with greatly reduced cost.

There is disclosed a perfectly plain FRESNEL zone lens. The perfectly plain FRESNEL zone lens includes a plurality of focusing units and a grid formed together with the focusing units by injection molding for example. The grid consists a plurality of cells. Each of the focusing units is disposed in a related one of the cells.

A lens device includes a base, groups of prism-like elements formed on the base and at least two alignment points formed on the base. Each of the groups and a related portion of the base form a lens. Each of the prism-like elements comprises an incidence surface in the form of a camber. The alignment points are used for alignment of a laser device with the lens device.

A frame is provided for highly-concentrated photovoltaic cells. The frame uses vertical and horizontal rods. Connectors are fixed at where the vertical and horizontal rods connect. The frame is constructed with the rods and connectors coordinated with fixing components. Thus, solar cell receivers can be directly set at any place on the frame; and the frame can be easily constructed and safely moved. Furthermore, location space is effectively used and weather resistance is achieved.

A thermoelectric generating module includes at least one thermoelectric unit and at least one light-concentrating unit. The thermoelectric unit has a first surface and a second surface disposed oppositely. The light-concentrating unit is disposed adjacent to the thermoelectric unit and concentrates light on the first surface of the thermoelectric unit.
