Abstract

Un film protecteur pour cellule solaire, selon la présente invention, est un film séparable qui peut être fixé/détaché et permet à la surface d'une cellule solaire d'être toujours maintenue dans le meilleur état en permettant de ne changer le film protecteur que lorsque la surface de la cellule solaire est contaminée ou endommagée, sans qu'il ne soit nécessaire de remplacer la totalité de la cellule solaire comme dans des procédés classiques. En même temps, le film protecteur a pour effet d'augmenter significativement l'efficacité de conversion d'énergie d'une cellule solaire par inhibition de la réflexion de la lumière et par conséquent d'augmenter la quantité de lumière incidente. De plus, étant donné que l'effet de motif qui a été largement utilisé pour des films antireflet n'est plus nécessaire, il existe de nombreux avantages en termes de coût et de maintenance.
