摘要:
This device comprises the following stack of layers: a first substrate having a glass function (V1); a first electronically conductive layer (TCC1) with an associated current feed; an electroactive system (EA); a second electronically conductive layer (TCC2) with an associated current feed; and a second substrate having a glass function (V2). Each current feed is constituted by a continuous conductive strip (1-1a; 2-2a) applied to the associated electronically conductive layer, said conductive strip being positioned over the entire perimeter or substantially over the entire perimeter of said layer (TCC1; TCC2) so as to strengthen the conductivity thereof and being connected to the electrical power supply via one of its ends.
