Abstract: This layered element, in particular for a photovoltaic device, includes a polymer layer, a moisture-sensitive layer, and a protective coating forming a moisture barrier inserted between the polymer layer and the moisture-sensitive layer. The protective coating includes an antireflection multilayer comprising at least two thin layers differing in refractive index from each other.

Abstract: 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.

Abstract: The subject of the invention is a transparent substrate (6), especially glass substrate, comprising an antireflection coating on at least one of its faces, which is made of a multilayer (A) of thin layers having alternately high and low refractive indices. The multilayer is characterized in that the high-index first layer (1) and/or the high-index third layer (3) are based on a zinc tin mixed oxide, with a ratio, expressed in atomic percent, of the tin to the zinc that is greater than 1.

Abstract: A method of supplying an electrically controllable system having variable optical/energy properties in transmission or in reflection, including at least one carrier substrate with a multilayer that allows migration of active species, including at least two active layers separated by an electrolyte, the multilayer being placed between two electrodes connected respectively to upper and lower current leads respectively. In addition to a constant first energy potential, a time-varying second energy potential is applied between the current leads, the first and second energy potentials being designed to ensure switching between two states having different optical/energy properties in transmission or reflection.
