Improve the Performance of Porous Silicon for Solar Application by Imbedding of Aloe Vera Nanoparticle

Abstract

This work is concerned with the fabrication of nanocrystalline porous silicon (PSi) by electrochemical etching method . Aloe Vera (NPs) have been prepared by simple chemical method.  And study of the effect of (Aloe Vera) on the (p-PSi and n-Psi) by using the drop casting technique procedure at a temperature of 50 ºC. Optical properties of Aloe Vera nanoparticles was UV–Vis spectrophotometer, FTIR. results of the current–voltage (I-V) test manifested that the maximum power conversion efficiency (PCE) of the solar cell and the filling factor for p-PSi, n-PSi were 0.67%,20.80% and 2.029%, 29.74% respectively. The diffusion of Aloe vera NPs on the PSi hetrojunction  assures that there was an improvement upon their properties.
