SOLAR CELL WITH A SURFACE STRUCTURE OF REDUCING REFLECTION RATIO AND METHOD FOR MANUFACTURING THE SAME

摘要

It provides a solar cell and a manufacturing method having a surface structure for reducing the reflectivity. The solar cell comprises a silicon substrate. Silicon substrate, i) comprises a first surface, and ii) a second surface facing the opposite direction as the first surface in which light is incident. The first surface toward the second surface, forming an outstretched least one opening, the first opening extending direction is inclined with respect to the first surface. ; Solar cells, etching, defects, light reflection preventive film, a silicon substrate
