A solar cell of improved conversion efficiency and a process of making it are disclosed. The solar cell is designed to trap incident light within the cell by multiple internal reflections and thus increases the absorption of light in the cell. The solar cell is formed with a plurality of spaced parallel grooves on both the front and the back surfaces. The direction of the grooves on the front surface is at an angle with respect to the direction of the grooves on the back surface.
