The method involves depositing resin (20) on an active surface of a photovoltaic cell (10). The resin is textured on the active surface with geometric patterns (31). The active surface is textured by eliminating the deposited resin. The deposition of the resin is preceded by pre-texturing of the resin on a depositing tool i.e. printing roller (30), and the texturing of the resin on the active surface is simultaneous with the deposition of the resin on the active surface, and the deposition and texturing of the resin are performed using a flexography or offset printing process. Procédé de texturation d'une face active d'une cellule photovoltaïque (10) en silicium monocristallin ou polycristallin comprenant les étapes consistant à déposer une résine (20) sur ladite face active, texturer la résine (20) sur cette face active avec des motifs géométriques, et texturer ladite face active en éliminant la résine (20) déposée, l'étape de dépose de la résine (20) étant précédée par une étape de pré-texturation de la résine (20) sur un outil de dépose (30), et l'étape de texturation de la résine (20) étant simultanée avec l'étape de dépose de la résine (20).
