TRANSPARENT SUBSTRATE FOR A SOLAR CELL HAVING A BROADBAND ANTI-REFLECTIVE MULTILAYERED COATING THEREON AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to a broadband anti-reflective, transparent substrate for a solar cell, more specifically, a broadband (350 to 1,100 nm wavelength) anti-reflective, transparent substrate for a solar cell that is a transparent substrate applicable to the solar cell's outermost surface (solar light-receiving surface) and has a multilayered coating of six (6) or more coating layers that are formed by alternately depositing a high-refractive material layer and a low-refractive material layer sequentially on its surface, whereby it shows a broadband (350 to 1,100 nm wavelength) anti-reflective function and increases the transmittance of light in a near-infrared region as well as a visible light region while it decreases transmittance of light in an infrared region which causes deterioration of the solar cell without contributing to electricity generation of the solar cell, and thus the efficiency of the solar cell can be improved; and a method for preparing the same.
