The present invention provides an improved thin film solar cell, wherein at least one additional resistive transparent conductive oxide (TCO) layer is incorporated into the solar cell. The additional resistive TCO electrically separates the conductive TCO layers acting as electrodes of such a cell and thus decreases or prevents performance losses. Furthermore, methods for the production of such solar cells are disclosed.

摘要:
Process for the production of a composite sheet (90) comprising a cellular core (41) and at least one outer layer (42) by bonding the outer layer (42) to the cellular core (41), for example with the aid of an adhesive film (84) under pressure and at elevated temperature, where the adhesive film (84) may initially extend over the entire surface and breaks up in the region of the honeycomb interior under the action of heat and on exposure to a gaseous medium, concentrating at the points of contact between the cellular core (41) and the outer layer (42). The outer layer (42) itself has an adhesive layer or an adhesive film (83) on the side facing the cellular core. The outer layer bonds to the cellular core under pressure and at elevated temperature.
摘要:
A composite panel comprising a core (12) and at least one outer sheet (14) which is adhesively bonded to the core is such that the composite panel (10) is shape-formed creating at least one radius of bending (24b) in the outer layer (14). The core (12) has a cellular structure and is bonded to the outer layer (14) at least by one visco-elastic adhesive layer (16) applied over the entire inner surface of the outer layer (14). The combination of the honeycomb structure of the core and the adhesive layer with the mentioned properties attaching the core to the outer sheet leads to a composite panel that may be shaped quickly and at favorable cost, without the outer layers being damaged or the stength being significantly reduced. As a result of the large area visco-elastic bonding a higher resistance to delamination, debonding due to vibration, corrosion and moisture is achieved.
摘要:
Process and equipment for the production of an expanded honeycomb core from strips (10) coated at uniform intervals with strips of adhesive (6), in which the strips (10) with their adhesive strips (6) parallel and in staggered positions are stacked on top of one another and adhesively bonded together under pressure and if necessary at an elevated temperature, the stack (40) so formed being subsequently expanded, consists in the following: a strip (10) passes over a position detector (24), which from the adhesive strips (6) determines its position relative to a first end (P) of a stack (40), and which controls a positioning drive (25) and a cutting device (26). The positioning drive (25) positions the strip (10) relative to the stack (40) at its end (P), and the strip (10) is held fast. Beginning from end (P), the strip (10) is progressively bonded in the direction of the other end (Q) to the previously stacked and underlying strip (10') in such a way that the adhesive strips (6) on strip (10) lie in-between those on the underlying strip (10'). Shortly before being bonded at the other end (Q), the strip (10) is cut by the cutting device (26) to a predetermined length limited by the ends (P. Q), which determines the desired width of the honeycomb core to be produced. The process is then repeated.
