Title (EN) PASTE COMPOSITION AND SOLAR CELL ELEMENT USING SAME
(FR) COMPOSITION DE PÂTE ET ÉLÉMENT DE CELLULE SOLAIRE L’UTILISANT
(JA) ペースト組成物およびそれを用いた太陽電池素子
Abstract: front page image
(EN)Provided are a paste composition which can improve rear plane electrode adhesiveness and suppress peeling of an aluminum electrode layer, and a solar cell element provided with an electrode formed by using such composition. The paste composition is provided for forming the electrode (8) on a silicon semiconductor substrate (1). The paste composition includes an aluminum powder, an organic vehicle and a tackifier. The solar cell element is provided with the electrode (8) which is formed by applying the paste composition having the above mentioned features on the silicon semiconductor substrate (1) and baking the substrate.
(FR)La présente invention concerne une composition de pâte qui peut améliorer l’adhérence d’une électrode de plan arrière et supprimer l’écaillage d’une couche d’électrode d’aluminium, et une cellule solaire comportant une électrode constituée d'une telle composition. La composition de pâte sert à former une électrode (8) sur un substrat de semi-conducteur en silicium (1). La composition de pâte comprend une poudre d’aluminium, un véhicule organique et un agent poisseux. L’élément de cellule solaire comporte l’électrode (8) obtenue en appliquant la composition de pâte présentant les caractéristiques susmentionnées sur le substrat semi-conducteur en silicium (1) et en cuisant le substrat.
(JA) 裏面電極の密着性を向上させ、アルミニウム電極層の剥離を抑制することが可能なペースト組成物と、その組成物を用いて形成された電極を備えた太陽電池素子を提供する。ペースト組成物は、シリコン半導体基板(1)の上に電極(8)を形成するためのペースト組成物であって、アルミニウム粉末と、有機質ビヒクルと、粘着付与剤とを含む。太陽電池素子は、上述の特徴を有するペースト組成物をシリコン半導体基板(1)の上に塗布した後、焼成することにより形成した電極(8)を備える。
