Purpose: The goal of this paper is to evaluate the strategic perspectives of polycrystalline silicon texturisation according to custom foresight methodology. The texturing type was the technology division criterion. Thus, in the paper three technologies, as following: polycrystalline silicon texturisation by alkaline etching, laser treatment and laser treatment with chemical etching were compared. Design/methodology/approach: In the framework of the foresight-materials science research, a foresight matrices set was prepared, the strategic development tracks were determined, as well as materials science experiments using a Nd:YAG laser, a scanning electron microscope, a confocal laser scanning microscope and a spectrophotometer were conducted. Finally, on the basis of the obtained results the technology roadmaps were prepared. Findings: The carried out research pointed out the industrial importance of polycrystalline silicon texturisation and good perspectives for these technology groups. Research limitations/implications: Research concerning polycrystalline silicon texturisation constitute a part of a larger research project aimed at identifying, researching, and characterising the priority innovative technologies in the field of materials surface engineering. Practical implications: The presented results of experimental materials science research were proved the significant positive impact of texturisation on the structure and mechanical properties of polycrystalline silicon surface layers, which leads to the justification of their including into the set of priority innovative technologies recommended for application in industrial practice. Originality/value: The novelty of this paper is to evaluate the value of polycrystalline silicon texturisation in the background environment with their future development perspectives determination.
