چکیده
In this reaserch, CdTe based thin film solar cell has been investigated under AM 1.5 ghobal spectrum with using Solar Cell Capacitance Simulator-1D (SCAPS-1D) software. Initially, solar cells with nanostructured FTO/TiO2/n-CdSe/p-CdTe were considered as the elementary cells and FTO/ TiO2/n-CdSe/p- CdSe1_xTex/p-CdTe as the upgraded cells. The purpose of this study was to investigate the key role of layer CdSe xTe 1-x. The results of the analyzes showed that the presence of CdSe xTe1- x nanostructured layer, between p- type CdTe absorber layer and n- type CdSe layer increased PCE from 14.05% to 21.98%, JSC from 20.42. mA/ cm2 to 26.06 mA/cm2, FF from 54.73% to 57.69% and VOC from 1.25 V to 1.46 V compared to the elementary cell.
