Purpose: Surface texturisation is a common technological process in solar cell manufacturing aiming at a reduction of the light reflection losses. The standard alkaline texturing of multicrystalline silicon for solar cells is not effective because of random orientation of the grains. In this paper a method of laser texturisation has been proposed to overcome these difficulties. Design/methodology/approach: The microstructure of laser textured surface was investigated by DSM 940 OPTON scanning electron microscope (SEM). Electrical parameters of produced solar cells were characterized by measurements of I-V light characteristics under standard AM 1,5 radiation. Findings: The analysis performed in the paper revealed the existence of laser-damaged layer on the textured surface which has to be removed prior to successive technological steps to obtain solar cells of satisfactory performance. Research limitations/implications: It is suggested that future work should be done to develop a better post-scribe etching technique to remove the laser damaged layer. Originality/value: It seems to be very promising method since it can be applicable in industry.
