Embodiment approach 1

[0152] Embodiment 1: Components with Metal Substrates - Demonstrating Bonding Quality, Durability, Electrical Safety and Fire Safety:

[0153] A module M3 is produced by known lamination methods, for example according to EP 0769818 A2, which comprises the following layer stack:

[0154] a) 50 μm ETFE membrane from Dupont (surface treated to attach to EVA)

[0155] b) Two EVA Vistasolar 486.10 membranes (thickness + / - 460μm) stacked

[0156] c) 50 μm PEN film supporting the active layer (e.g. TCO / pin / back electrode / adhesive layer / adhesive to PEN), and Al at the back side of the PEN film 2 o 3 Coating (reactive sputtering)

[0157] d) Coextruded film of "50 μm EAA Primacor 1410 / 900 μm VLDPE Exact 0203 / 50 μm EAA Primacor 1410" containing (average value, not added to all layers to avoid neutralization of acrylic functional groups) antioxidant (0.3% from Ciba Irganox B225), HALS (0.3% Tinuvin 770 and 0.3% Chimassorb 944), acid scavengers, pigments (5% TiO 2 Kronos 2220), 24% ...

Embodiment approach 2

[0167] Embodiment 2: Demonstration of fire-resistant safety of TPO water-resistant membrane (10) and plastic PV cell (110)

Embodiment 1

[0169] Sample A is a polyester reinforced 1.5mm multilayer TPO water resistant membrane (10) according to the invention with a halogenated flame retardant. The composition of the multilayer diaphragm is as follows:

[0170] - Top layer of 300μm Hifax CA 10A with conventional stabilizers and pigments and 25% Saytex BT93 halogenated flame retardant with 10% Sb 2 o 3 .

[0171] - Intermediate layer of 600 μm Hifax CA 10A with conventional stabilizers and pigments and 17% Saytex 8010 halogenated flame retardant with 6% Sb 2 o 3 .

[0172] - 2*21100dTEx polyester reinforcement.

[0173] - Lower layer of 600μm Hifax CA 10A with conventional stabilizers and pigments and 17% Saytex 8010 halogenated flame retardant with 6% Sb 2 o 3 .

[0174] The burnt surface after the fire resistance test is 3200mm 2 .

[0175] Sample B was the same TPO water resistant membrane (10) with the following layer stack laminated on top of it:

[0176] a) 50 μm ETFE, which is surface treated to a...

Abstract

The flexible photovoltaic module (1) with good external fire performance comprises photovoltaic cells (1c) on plastic substrate and plastic sheet or adhesive layer (1d) under cell based on polyolefin, and / or copolymer of ethylene or propylene with vinyl acetate or (meth) acrylates or neutralized acrylic acids (ionomers). The plastic sheet or adhesive layer contains at least 50 (preferably 100) g / m2 halogenated (preferably brominated) flame retardant. The layers above plastic sheet allow release of flame poisoning substances coming from plastic sheet when fire is set to module.

Description

technical field [0001] The present invention relates to articles of manufacture and cost-effective methods of manufacturing integrated optoelectronic components for consumer and protective applications. Background technique [0002] In order to obtain cost-effective optoelectronic applications, it is necessary to integrate the components in the application and / or to speed up the production steps and / or to use cost-effective methods and materials. [0003] For shielding applications optoelectronic integrated protective membranes already exist and are described in DE 29824045U1 and WO2004066324A2: To obtain a shield (to which optoelectronic components are connected) a flexible lightweight optoelectronic with factory lamination on top is used (PV) The water-resistant membrane of the module is used as a water-resistant membrane. Such PV-integrated water-resistant membranes are manufactured by companies such as SIT (Solar Integrated) in the US or Alwitra in Germany. They consis...
