Formation of the nanoporous Si structure of solar cell with using a model representation

Abstract

In this study, to obtain frontal functional nanolayers of solar cells, an analysis of existing models of PSi was made. In order to achieve a low integral reflection coefficient of a textured Si surface, which can be further used as an efficient anti-reflective coating, a number of experiments were performed to establish the influence of technological conditions on the morphology of porous Si fabricated by electrochemical etching. The results of SEM studies showed that the porous Si surface obtained does not contain noticeable damage or cracking, which indicates the correct choice of technological modes of anodic etching. The obtained porous textures characterized by minimal integral reflection, which is a necessary condition for creating the front surface of Si-based solar cells.
