ANTI-REFLECTIVE COATING FILM, SOLAR CELL INCLUDING THE ANTI-REFLECTIVE COATING FILM, AND METHOD OF PREDICTING STRENGTH OF THE ANTI-REFLECTIVE COATING FILM FOR THE SOLAR CELL

摘要

An anti-reflective coating film is formed from a coating solution composition that includes a silane-based precursor. When measured via Fourier Transform Infrared (FT-IR) Spectroscopy using a wavelength of 1064 nm, the coating solution composition exhibits a peak intensity ratio I_B/I_A and a peak intensity ratio I_C/I_A of equal to or greater than 0.47, respectively. The peak intensity I_B is in a range of about 930 cm⁻¹ to about 960 cm⁻¹, the peak intensity I_A is in a range of about 1110 cm⁻¹ to about 1130 cm⁻¹, and the peak intensity I_C is in a range of about 1020 cm⁻¹ to about 1050 cm⁻¹. A solar cell including the anti-reflective coating film, and a method of predicting the strength of the anti-reflective coating film for the solar cell have been disclosed.
