摘要

<span style="font-family:Verdana;">A theoretical study of a polysilicon solar cell with a radial junction in </span><span style="font-family:Verdana;">static</span><span style="font-family:Verdana;"> 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.</span><span><span><span style="font-family:;" "=""> </span></span></span><span><span><span style="font-family:;" "=""><span style="font-family:Verdana;">The wavelength and structural parameters (base radius, </span><span><span style="font-family:Verdana;">base thickness </span><span style="font-family:Verdana;">and</span><span style="font-family:Verdana;"> wavelength) influences on photocurrent density and quantum </span></span><span style="font-family:Verdana;">efficiency are carried out and examined.</span></span></span></span>
