Abstract: In this article, we studied the influence of an external electric field applied in the base of a solar cell on its various electric parameters when it is illuminated by a monochromatic light. We have taken into account the actual values of intrinsic recombination velocities at the junction and the back face. This study revealed that when the electric field increases, the excess minority carrier density décreuses; on the other side, photocurrent, phototension, power, and capacitance increase with it. The application of the electric field in the base could improve the efficiency of the solar cell.
