TEXTURED COATING WITH VARIOUS FEATURE SIZES MADE BY USING MULTIPLE-AGENT ETCHANT FOR THIN-FILM SOLAR CELLS AND/OR METHODS OF MAKING THE SAME

摘要

Certain example embodiments of this invention relate to solar cell devices, and/or methods of making the same. More particularly, certain example embodiments relate to a front transparent conductive electrode for solar cell devices (e.g., micro-morph silicon thin-film solar cells), and/or methods of making the same. The electrode of certain example embodiments may include a textured transparent conductive oxide (TCO) layer. The textured layer and/or coating may include at least two feature sizes, wherein at least one type of feature is comparable in size to the wavelength of solar light absorbed by the amorphous portion of the micro-morph silicon solar cell, and the other feature size being comparable to that of micro-crystalline portion. Double- agent etchants may be used to produce such different features sizes. Using a textured TCO-based layer having different feature sizes may improve the efficiency of the solar cell.
