1. A solar energy collecting module, comprising:
- a substrate comprising a first surface, a second surface and a plurality of lateral surfaces, wherein the first surface faces the second surface, the lateral surfaces are adjacent to the first and second surfaces, and a first micro-structure is formed on the second surface;
at least one solar cell disposed on one of the lateral surfaces, arranged such that solar light penetrates the first surface and is refracted or reflected by the first micro-structure on the second surface to leave the substrate via the lateral surface on which the solar cell is disposed and be absorbed by the solar cell; and
a micro/nano-scale structure comprising;
a micro/nano layer formed on the first surface of the substrate; and
a metal layer formed on the micro/nano layer,wherein the first micro-structure comprises a plurality of strips, wherein each of the strips extends in a direction parallel to the lateral surface on which the solar cell is disposed, and a cross section of each strip is triangular,wherein a vertex angle of the triangular of each of the strips is divided into an angle A and an angle B by a vertical line extending from an apex, the angle A is 80 degrees, and the angle B is 40-80 degrees.

Abstract
A solar energy collecting system includes a substrate and at least one solar chip. The substrate includes a first surface, a second surface and a plurality of lateral surfaces, wherein the first surface faces the second surface, the lateral surfaces are adjacent to the first and second surfaces, and a first micro structure is formed on the first or the second surface. The solar chip is near one of the lateral surfaces. Solar light penetrates the first and the second surface and is refracted or reflected by the first micro structure to leave the substrate via the lateral surface and be absorbed by the solar chip.
