Title (EN) P-TYPE PERC DOUBLE-SIDED SOLAR CELL, ASSEMBLY THEREOF AND SYSTEM THEREOF
(FR) CELLULE SOLAIRE À DOUBLE FACE PERC DE TYPE P, SON MONTAGE ET SON SYSTÈME
(ZH) P型PERC双面太阳能电池及其组件、系统
Abstract:
(EN) Provided is a P-type PERC double-sided solar cell, comprising back sliver electrodes (1), back aluminum gate lines (2), a back passivation layer (3), P-type silicon (4), an N-type emitter (5), a front silicon nitride film (6), and a front silver electrode (7) in sequence. The back sliver electrodes are vertically connected to the back aluminum gate lines; intervals between the back aluminum gate lines are not equal; a first laser grooving area is formed by performing laser grooving on the back passivation layer; the back aluminum gate lines are connected to the P-type silicon by means of the first laser grooving area; the first laser grooving area comprises multiple groups of first laser grooving units which are provided horizontally; each group of first laser grooving units comprises one or more first laser grooving bodies which are provided horizontally; the back aluminum gate lines are vertical to the first laser grooving bodies.
(FR) L'invention concerne une cellule solaire à double face PERC de type P, comprenant des électrodes d'argent arrière (1), des lignes de grille en aluminium arrière (2), une couche de passivation arrière (3), du silicium de type P (4), un émetteur de type N (5), un film de nitrure de silicium avant (6) et une électrode d'argent avant (7) en séquence. Les électrodes d'argent arrière sont reliées verticalement aux lignes de grille en aluminium arrière ; des intervalles entre les lignes de grille en aluminium arrière ne sont pas égaux ; une première zone de rainurage laser est formée par réalisation d'un rainurage laser sur la couche de passivation arrière ; les lignes de grille en aluminium arrière sont reliées au silicium de type P au moyen de la première zone de rainurage laser ; la première zone de rainurage laser comprend de multiples groupes de premières unités de rainurage laser qui sont disposées horizontalement ; chaque groupe de premières unités de rainurage laser comprend un ou plusieurs premiers corps de rainurage laser qui sont disposés horizontalement ; les lignes de grille en aluminium arrière sont verticales par rapport aux premiers corps de rainurage laser.
(ZH) 提供一种P型PERC双面太阳能电池,依次包括背银电极(1)、背铝栅线(2)、背面钝化层(3)、P型硅(4)、N型发射极(5)、正面氮化硅膜(6)和正银电极(7),背银电极与背铝栅线垂直连接,背铝栅线之间的间距不相等;对背面钝化层通过激光开槽形成第一激光开槽区,背铝栅线通过第一激光开槽区与P型硅相连;第一激光开槽区包括多组水平方向设置的第一激光开槽单元,每一组第一激光开槽单元包括一个或多个水平方向设置的第一激光开槽体,背铝栅线与第一激光开槽体垂直。
