Wherein, the concentrating light guiding unit comprises at least a plane of the top edge, and an abutting surface of the bottom edge, and an oblique plane or a curved surface extending downward from the plane to the abutting surface.俾 Place the abutting surface on a plurality of solar cells arranged at intervals, and receive light by a plane and reflect by oblique plane or oblique curved surface to achieve superior light guiding and concentrating effects, thereby improving the power generation efficiency of the solar device, and The packaging process for solar installations is simplified, significantly reducing the cost of manufacturing.

In the above-mentioned solar cell high-concentration concentrating device, the area of the abutting surface of the bottom edge of the concentrating light guiding unit is equal to or smaller than that of the solar cell.

In the above-mentioned solar cell high-concentration concentrating device, the oblique plane or the oblique curved surface of the concentrating light guiding unit may be externally plated with a metal reflective layer or a dielectric reflective layer to constitute a reflection effect.

In the above-mentioned solar cell high-concentration concentrating device, the abutting surface of the bottom edge of the concentrating light guiding unit and the solar cell are bonded with a light-transmitting glue to bond the glass brick to the solar cell.
