Abstract

Method for manufacturing photovoltaic sub-cells of various shapes, from a photovoltaic cell (C0) with interdigitated rear contact, comprising a substrate (1) based on crystalline silicon, the method combining ablation (A1) by laser irradiation (L) of a first part of the substrate (1) with selective chemical etching of a second part (S2) of the substrate (1).
