Different methods are used to improve solar cell efficiency. In this paper, we use triangular grooves on the upper surface of the silicon cell to reduce outside reflection on the surface of the cell and increase the internal reflection withinthe cell by putting mirrors on the four sides of the cell. We compare the performance of this cell using the Zemax program for different aspect ratio (A.R) values and incident angles of the rays against another cell with triangular grooves and no mirrors. For A.R=1,with a parallel incidence angle of the triangular grooves of"θ" ^"°" = 〖"50" 〗^"°" , the number of rays that hit the detector is equal to2998 in the case of using mirrors. However, it was equal to 1200 without mirrors with across incidence angle of the triangular grooves of"θ" ^"°" = 〖"20" 〗^"°" and A.R =1thenumber of rays for the case using mirrors was equal to 2960,and 1000 without mirrors.
