%X In this paper, we investigate theoretically a radial
n<sup>+</sup>/p silicon solar cell in steady state and monochromatic
illumination. The purpose of this work is to analyze the effect of the cell
base radius on its electrical parameters. The continuity equation in
cylindrical coordinates is established and solved based on Bessel functions and
boundaries conditions; this led us to the photovoltage and photocurrent density
in the cell. The open circuit voltage and the short circuit current density are
then deduced and analyzed considering the base radius. Based on J-V and P-V
curves, series and shunt resistances, fill factor and maximum power point are
derived and the conversion efficiency of the cell is deduced. We showed that
short circuit current density, maximum power, conversion efficiency and shunt
resistance decrease with increasing base radius contrary to the open circuit
voltage, the fill factor and the series resistance.
