SOLAR MODULE WITH REDUCED POWER LOSS AND PROCESS FOR THE PRODUCTION THEREOF

摘要

A solar module is described. The solar module has 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. 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 into the absorber zone and/or the diffusion of dopant ions from the absorber zone into the bonding layer. A process for producing such a solar module is also described.

1. A solar module comprising:
a laminated composite of two substrates bonded to one another by at least one adhesive layer, serially connected solar cells between the two substrates, each solar cell comprising an absorber zone, made of a semiconducting material, between a front electrode arranged on a light-entry side of the absorber zone and a rear electrode, and a diffusion barrier, differing from the front electrode, situated between the absorber zone and the adhesive layer, said diffusion barrier is being configured to inhibit diffusion of water molecules out of the adhesive layer into the absorber zone and/or diffusion of dopant ions out of the absorber zone into the adhesive layer.
