Abstract
Porous silicon is advisable to get by electrochemical etching. The porosity of the obtained samples was about 70%. The thickness of the porous layer is (150–250) nm. The results of measurement of a reflectance of solar cells with different layer thicknesses of porous silicon show increased absorptive capacity of the porous silicon with increasing thickness, which directly indicates the possibility of using this material in solar cells. The porous silicon layer thickness from 70 microns has a greater dispersibility than the layers of lesser thickness. Thus, the use of porous silicon as a raw material for solar cells has excellent prospects. Such structures have a clear advantage over traditional and greatly improved technology to produce photovoltaic devices.
