要約
(EN)
In the present invention, a region where a rear surface electrode layer and a transparent electrode layer are short-circuited due to laser heat, said region being at the periphery of a thin film solar cell, is removed from a solar cell element by a process step easier than conventional process steps. This thin film solar cell is configured by laminating a rear surface electrode layer, a light absorbing layer, and a transparent electrode layer on a substrate, dividing the laminate into a plurality of unit cells using scribe grooves, and connecting the unit cells in series. On the inner side of an end portion of the solar cell side orthogonal to the scribe grooves, an orthogonal groove is formed, said orthogonal groove being orthogonal to the scribe grooves, and having a portion above the rear surface electrode removed therefrom. Furthermore, this method for manufacturing the thin film solar cell has: a step wherein laser light is radiated to the solar cell elements at the end portion of the side orthogonal to the scribe grooves, and a new end surface is formed by removing the rear surface electrode layer, the light absorbing layer, and the transparent electrode layer, which have been irradiated with the laser light; and a step wherein, on the inner side of the new end surface, the orthogonal groove having the portion above the rear surface electrode layer removed therefrom is mechanically formed orthogonal to the scribe grooves.

Selon la présente invention, une région, où une couche d'électrode de surface arrière et une couche d'électrode transparente sont court-circuitées en raison de la chaleur générée par un laser, ladite région étant à la périphérie d'une cellule solaire à couche mince, est retirée d'un élément de cellule solaire par une étape de traitement plus facile que les étapes de traitement classiques. Cette cellule solaire à couche mince est configurée par stratification d'une couche d'électrode de surface arrière, d'une couche d'absorption de lumière et d'une couche d'électrode transparente sur un substrat, division du stratifié en une pluralité de cellules unitaires en utilisant des rainures tracées, et connexion des cellules unitaires en série. Sur le côté intérieur d'une partie d'extrémité du côté cellule solaire orthogonal aux rainures tracées, une rainure orthogonale est formée, ladite rainure orthogonale étant orthogonale aux rainures tracées, et ayant une partie au-dessus de l'électrode de surface arrière retirée de celle-ci. De plus, ce procédé de fabrication de cellule solaire à couche mince comprend les étapes suivantes : de la lumière laser est rayonnée sur les éléments de cellule solaire au niveau de la partie d'extrémité sur le côté orthogonal aux rainures tracées, et une nouvelle surface d'extrémité est formée par élimination de la couche d'électrode de surface arrière, de la couche d'absorption de lumière et de la couche d'électrode transparente, qui ont été exposées à la lumière laser ; sur le côté intérieur de la nouvelle surface d'extrémité, la rainure orthogonale ayant la partie au-dessus de la couche d'électrode de surface arrière retirée de celle-ci est mécaniquement formée de manière orthogonale aux rainures tracées.
