PURPOSE:To improve the conversion efficiency of a solar cell by applying a frit containing specific ingredients, in manufacturing an enamel substrate for the solar cell applying the frit on at least one side of stainless steel plate to form a glass layer. CONSTITUTION:A frit containing 40-65 wt.% of SiO2, 10-30 wt.% of Na2O, 6-20 wt.% of B2O3, and 10-35wt.% of PbO is applied in manufacture of the substrate for the solar cell. In addition, 2-5 wt.% of K2O, 5-8wt.% of TiO2, and 3.5-3.0 wt.% of CaO may be added as components according to demand. In such the application, the a-Si substrate for solar cell has necessary surface smoothness and flexural rigitity and improved conversion efficiency of the solar cell.
