%X Inexpensive silicon solar cell utilizes nanotechnology offers great possibility to enhance the conversion efficiency and reduce the maintenance requirements as well. Moreover, the large surface area of the nanostructured solar cell enables this cell to reduce the number of the required cells. The surface of ordinary solar cell has been reconstructed by electrochemical etching in suitable cell. It is found that the etching time and current density have optimum values to obtain higher conversion efficiency. Effects of these two parameters on the optoelectronic properties of the solar cell have been studied. Spectroscopic methods involving Raman and photoluminescence emission were carried out on the reconstructed surface of the solar cell.Fitting of Raman line shape with theoretical quantum confinement model implies that nanostructure of mean value of 6 nm was established. While the surface morphology investigation reveal synthesize of a pore-like structure separated by thin walls consisting silicon nanostructures.
