Fabrication solar cell device from CdTe nanoparticles suspension

Abstract EN

In the present study ,nanoparticles cadmium telluride (cdte) on si p-type substrates heterojunction solar cell has been made by using pulse laser ablation PLA.Qswitching, Nd : YAG laser (500mj,9ns),wavelength 532 nm with number of pluses(60 and 120)pulse using of the bulk materials target in methanol solution.

Optical, structure characterization of Nanoparticles suspensions studies by using UV-Vis spectrophotometry, X-ray diffraction (XRD), transmission electron microscopy (TEM).The photovoltaic characteristics included short circuit current and open circuit voltage (ISC–VOC), where the maximum (Jsc) and(voc)obtained were 25.3 mAcm-2 and 144.9mv respectively.

The fill factor(ff) was( 0.42) and the conversion efficiency(1.5 % ).
