Abstract
Photovoltaic conversion is a photo-electronic process that involves the interaction between a photo and
an electron. The subject is to present a study on the physical principle of operation of a photovoltaic cell
based on silicon. The external parameters that we have determined from a photovoltaic model are the
short-circuit current (Jsc), the open-circuit voltage (Voc) and the photovoltaic conversion efficiency (K), we
simulate the photovoltaic parameters by the Solar Cell Capacitance Simulator structures (SCAPS-1D)
software whose mathematical model is based on solving the equations of Poisson and continuity of elec-
trons and holes. We used two structures to carry out this study, the first ITO/CdS/Si and the second
ZnO/Si/CdS, after having noted their current-voltage characteristic (J-V). In this paper we studied the
effect of the temperature and the doping concentration on the two structures of heterojunction solar cell.
The highest performance value for the ZnO/CdS/Si heterojunction solar cell was simulated as 29.3 %. The
performance value for the ITO/CdS/Si structure was increased to 29.7 % with the impact of the ITO antire-
flective layer
