Certain example embodiments of this invention relate to a front electrode for solar cell devices (e.g., amorphous silicon or a-Si solar cell devices), and/or methods of making the same. Advantageously, certain example embodiments include a layer that acts as an etch-stop layer. In certain example embodiments, the blocking layer is provided between a transparent conductive oxide layer including AZO and a conductive layer. In certain example embodiments, a weak acid may be used to texture the layer including AZO. A semiconductor may be provided over the textured layer including AZO. The blocking layer provided between the layer of AZO and the IR reflecting layer may be more resistant to etching by weak acids than the layer based on AZO. Therefore, in certain example embodiments, the blocking layer may substantially reduce the risk of the semiconductor coming into contact with the conductive layer (which may be based on Ag).
