Abstract

Two different wet etching solutions, NaOH 40% and Acid, were used for etching in tri-crystalline Silicon(Tri-Si) solar cell fabrication. The wafers etched in NaOH40% solution showed higher reflectance compared to the wafers etched in Acid solution after $SiN_x$ deposition. In light current-voltage results, the cells etched in Acid solution exhibited higher short circuit current and open circuit voltage than those of the cells etched in NaOH 40% solution. We have obtained 16.70% conversion efficiency in large area($156cm^2$) Tri-Si solar cells etched in Acid solution.
