Abstract[English]
Provided in the present invention are a localized-junction battery structure and a preparation method therefor. The method comprises the following steps: S1, performing texturing; S2, performing coating; S3, performing film patterning; S4, performing diffusion; and S5, performing post-treatment, so as to form a photovoltaic cell having a localized-junction structure. The localized-junction battery structure in the present invention can break through the limitation of transfer resistance in the prior art, thereby increasing an open-circuit voltage, reducing the transfer resistance and improving the efficiency.[French]
La présente invention concerne une structure de batterie à jonction localisée et son procédé de préparation. Le procédé comprend les étapes suivantes : S1, réalisation d'une texturation ; S2, réalisation d'un revêtement ; S3, réalisation d'une formation de motif de film ; S4, réalisation d'une diffusion ; et S5, réalisation d'un post-traitement, de façon à former une cellule photovoltaïque ayant une structure de jonction localisée. La structure de batterie à jonction localisée selon la présente invention peut dépasser la limitation de la résistance de transfert dans l'état de la technique, ce qui permet d'augmenter une tension de circuit ouvert, de réduire la résistance de transfert et d'améliorer l'efficacité.[Chinese]
