In this work, we have shown that we can reduce recombination current by the use of heterojunction cells with variable band gap in the space charge zone. We have seen that all the parameters of the graded layer are functions of the distance ( z ), we use the Joyce -Dixon Fermi approximation of full concentration to find n and p is ultimately the recombination rate , we have arrived to calculate the recombination current by integrating U (z) is a result we examined the variation of the photovoltaic parameter relative to the thickness of the graded layer . The study of recombination in a space charge zone, comprising a layer of transition variable bandgap and wide bandgap region shows that the recombination current decreases with decreasing of the thickness of the transition layer .
