The invention relates to a solar module having a laminated composite of two substrates bonded to one another by at least one bonding layer, between which substrates there are solar cells which are connected in series and which each have an absorber zone made of a semiconducting material between a front electrode arranged on a light entrance side of the absorber zone and a rear electrode, wherein a diffusion barrier differing from the front electrode is located between each absorber zone and the bonding layer and is designed to inhibit the diffusion of water molecules from the bonding layer (10) into the absorber zone and/or the diffusion of dopant ions from the absorber zone into the bonding layer. Furthermore, the invention relates to a process for producing such a solar module.

The invention relates to an electrochemical device (1) with electrocontrollable optical transmission and/or energy-related properties, of the type comprising two electrode claddings (4, 6) and, between them, an electrochemically active layer (6) made from a mineral material able to pass in a reversible manner between two states with different optical transmission and/or energy-related properties by insertion and deinsertion of ions. An electrolyte (8) is present between the electrochemically active layer and the second electrode cladding. The material of the electrochemically active layer is a material for which the insertion and deinsertion of ions during passages between the two states correspond to a variation of the plasma wavelength λ of the material and in that the material has, at the plasma wavelength λ, a bandwidth at mid-height ∆λ of the absorption spectrum that is less than or equal to 1 micron in the two states.
