Abstract

L'invention concerne un processus de collage de ruban adhésif de réparation pour une feuille arrière (7) de module photovoltaïque et son application. Lorsqu'une exception ne se produit que dans la feuille arrière (7), il n'est pas nécessaire pour remplacer tous les modules photovoltaïques. En réparant partiellement ou complètement la feuille arrière, des modules photovoltaïques endommagés peuvent fonctionner normalement pendant la période de garantie, de sorte que les valeurs des modules photovoltaïques sont efficacement renforcées et que la longévité des modules photovoltaïques est prolongée.
