A subject-matter of the invention is a conducting substrate (1) for a photovoltaic cell, comprising a carrier substrate (2) and an electrode coating (6) formed on the carrier substrate (2). The electrode coating (6) comprises a main molybdenum-based layer (8) formed on the carrier substrate (2), a barrier layer to selenization (10) formed on the main molybdenum-based layer (8) and, on the barrier layer to selenization (10), an upper layer (12) based on a metal M capable of forming, after sulfurization and/or selenization, an ohmic contact layer with a photoactive semiconducting material. The barrier layer to selenization (10) has a thickness of less than or equal to 50 nm, preferably of less than or equal to 30 nm, more preferably of less than or equal to 20 nm.
