Preparation and fabrication of (Mg,Sn) doped CdO/PSi solar cell by laser induced plasma

Abstract

The cadmium oxide films containing both tin and magnesium (Mg, Sn) were deposited on the p-type porous silicon bases at room temperature (300k) with pulsed laser sedimentation technology (PLD). The characteristics of the manufactured cells were studied, which include measuring short circuit current density (JSC) and open circuit voltage (VOC), where it was found that the highest value of short circuit current density was within (6.60mA / cm2) and open circuit voltage (0.54v). It was found that the efficiency of the solar cell increases with an increase in the percentage of vaccination from (0.59) for pure materials to reach (1.76%) for (n-CdO1-x: Snx / P-PSi) and (1. 64%) with respect to films (n-CdO1-X: MgX / P-PSi).
