It is demonstrated that the magnitude of saturation currents of p-n junctions in photovoltaic converters of laser radiation has a critical influence on the processes of current spreading between finger contacts and, consequently, largely determines the choice of the optimum design of the front contact grid. The optimum designs of contact grids for photovoltaic converters of laser radiation with different band gaps Eg are calculated by varying the value of spreading sheet resistance RSHEET and width Wm of finger contacts. Keywords: photovoltaic converters, solar cells, spreading resistance, contact resistance.
