SILICON SUBSTRATE FOR SOLAR BATTERY, MANUFACTURING APPARATUS THEREOF, MANUFACTURING METHOD THEREOF, AND SOLAR BATTERY

摘要

The present invention relates to a silicon substrate 10 for a solar battery, wherein the silicon substrate 10 comprises: a plurality of curves 13 constituted by concave parts 11 and convex parts 12 to absorb sunlight; and planes 14 connected to both edges of the curves to absorb sunlight and to be connected to other silicon substrates. Each of the curves 13 and each of the planes 14 have a thickness of 100 to 300µm, and each of the concave parts 11 or each of the convex parts 12 has a semi-circular shape. The curves 13 occupy 90% or more of the total area.
