Popis:	27th European Photovoltaic Solar Energy Conference and Exhibition; 766-771 The presented study provides a detailed insight for wet chemical texturing procedures of “cast-mono” or “mono-like” silicon substrates. Fundamental investigations establish the demand for adapted etching techniques in order to address the exceptional “cast-mono” surface properties. Fundamental evaluation parameters are texturing homogeneity, magnitude of effective surface reflectance and quality of produced texturing structures. The impact on solar cell characteristics, relevant processing steps and industrial application is discussed and interpreted with respect to material classifications and cost-effective manufacturing sequences.
