CA 2141946

The invention concerns a process and equipment for manufacturing laminated photovoltaic modules, where (a) a module- stack (2) formed by the system of solar cells, the encapsulating materials and the separating foils is deposited at the loading station (1) and where (b) the module-stack (2) is moved into the vacuum laminator (5) which thereupon is closed and evacuated, and, by pressing the heater plate (21) against the thermally conductive carrier plate (3), said stack is heated to the sof- tening point of the plastic sealing layers present in the encap- sulating materials, and where (c) following airing of the vacuum laminator (5) the heater plate (21) is not cooled and the formed composite (2') is moved into the hardening oven (10) and where (d) the hardened laminate (2") is then moved into the cooling zone (12) and (e) is removed from the manufacturing process at the removal station (14). The process stages (a) through (e) of the invention are carried out simultaneously and parallelly in timed manner.

Un procédé et un dispositif permettent de fabriquer des modules photovoltaïques à base d'agglomérés stratifiés. Selon ce procédé, (a) une pile modulaire (2) constituée par le système formant la cellule solaire, les matériaux d'encapsulage et les films de séparation empilés est transmise au poste de chargement (1); (b) la pile modulaire (2) est transportée jusqu'à la machine à stratifier sous vide (5), qui est ensuite fermée et mise sous vide, puis la pile modulaire (2) est chauffée par compression de la plaque de chauffage (21) sur la plaque thermoconductrice de support (3) jusqu'à la température de ramollissement des couches plastiques de scellement situées dans les matériaux d'encapsulage; (c) le composite (2') formé lorsque la machine à stratifier sous vide (5) est aérée, sans que la plaque de chauffage (21) soit refroidie à nouveau, est transporté jusqu'au four de trempe (10); (d) le stratifié trempé (2") est transporté jusqu'à la zone de refroidissement (12); et (e) à la fin du processus de fabrication, le stratifié est prélevé au niveau du poste d'extraction (14). Les étapes (a) à (e) du procédé sont effectuées cycliquement simultanément et parallèlement.
