Abstract: A solar cell concentrating apparatus includes a parabolic reflector focusing a beam of light on an array of photovoltaic cells to generate electric current. The photocell array includes a number of triangular shaped segments arranged in a polygon. Surrounding the triangular shaped segments is another set of solar cells, each having a trapezoidal shape. The trapezoidal cells each have a larger surface area than that of the adjacent triangular shaped cell. The electric current produced by each trapezoidal cell is approximately the same as that of the smaller triangular shaped cells, which are subject to more intense incident light due to the beam's Gaussian spot profile.
