ABSTRACT: A theoretical study of a polysilicon solar cell with a radial junction in static regime under monochromatic
illumination is presented in this paper. The junction radial solar cell
geometry is illustrated and described. The carriers’ diffusion equation is
established and solved under quasi-neutral base assumption with boundaries conditions
and Bessel equations. New analytical expressions of electrons and holes
photocurrent density and quantum efficiency are found. The
wavelength and structural parameters (base radius, base thickness and wavelength)
influences on photocurrent density and quantum efficiency are carried
out and examined.
