Definitions
- Photovoltaic modules with plasticized films based on polyvinyl acetal with high specific resistance are plasticized films based on polyvinyl acetal with high specific resistance
- the invention relates to the production of photovoltaic modules using plasticized films based on polyvinyl acetal with high resistivity.
- Photovoltaic modules consist of a photosensitive semiconductor layer, which is provided to protect against external influences with a transparent cover.
- a photosensitive semiconductor layer monocrystalline solar cells or polycrystalline, thin semiconductor layers can be used on a support.
- Thin-film solar modules consist of a photosensitive semiconductor layer coated on a mostly transparent plate, e.g. by vapor deposition, vapor deposition, sputtering or wet deposition is applied.
- Both systems are typically sandwiched between a pane of glass and a rigid, rear cover plate, e.g. laminated from glass or plastics using a transparent adhesive.
- the transparent adhesive must completely enclose the photosensitive semiconductor layer and its electrical connection lines, be UV-stable and insensitive to moisture and be completely bubble-free after the lamination process.
- thermosetting adhesive systems are the use of plasticized films based on polyvinyl acetals, such as the polyvinyl butyral (PVB) known from the manufacture of laminated glass.
- PVB polyvinyl butyral
- PVB films Processes for the production of solar modules by means of PVB films are, for. Example by DE 40 26 165 C2, DE 42 278 60 Al, DE 29 237 70 C2, DE 35 38 986 C2 or US 4,321,418.
- the use of PVB films in solar modules as composite safety glazings is known e.g. in DE 20 302 045 Ul, EP 1617487 Al, and DE 35 389 86 C2 discloses.
- these documents contain no information about the mechanical, chemical and electrical properties of the PVB films used.
- the electrical properties of the adhesive films are becoming increasingly important as the performance of the photosensitive semiconductor layers and the global spread of solar modules increases. Charge losses or even Short circuits of the semiconductor layer must also be extreme
- Photovoltaic modules are subjected to a variety of tests according to CEI 61215
- Adhesive films have an extremely high resistivity
- the object of the present invention is therefore to provide plasticized films based on polyvinyl acetal with high specific (electrical) resistance for the production of photovoltaic modules.
- films having an increased glass transition temperature Tg have an increased specific resistance. Without being bound by the theory, this is attributed to decreased ion mobility in a glassy or highly viscous environment.
- the present invention therefore relates to photovoltaic modules comprising a laminate of a) a transparent front cover b) one or more photosensitive semiconductor layers c) at least one plasticizer-containing polyvinyl acetal-based film and d) a rear cover wherein the plasticizer-containing, polyvinyl acetal-based Films c) have a glass transition temperature Tg of at least 20 0 C.
- the glass transition temperature Tg of the films used in the invention is preferably at least 22 0 C, 24 0 C, 26 0 C, 27 0 C, 30 0 C or 35 ° C.
- the maximum limit for the glass transition temperature Tg 40 0 C can be specified.
- the glass transition temperature Tg of plasticized films based on polyvinyl acetal is determined to a large extent by the proportion and the polarity or softening effect of the plasticizer used. Thus, the specific resistance of the film can be easily adjusted via the plasticizer.
- the films used according to the invention preferably have a specific resistance of at least 1E + 11 ohm.cm, preferably at least 5E + 11 ohm.cm, preferably 1E + 12 ohm.cm, preferably 5E + 12 ohm * cm, preferably 1E + 13, preferably 5E + 13 ohm * cm, preferably 1E + 14 ohm * cm.
