Title:
太陽電池素子
Document Type and Number:
Japanese Patent JP6585227
Kind Code:
B2
Abstract:
The solar cell element includes a semiconductor substrate with first and second surfaces, a passivation layer being in contact with the second surface, a protective layer located on the passivation layer, a bus bar electrode, and a collecting electrode. The bus bar electrode is in contact with the second surface in a first gap portion penetrating the passivation layer and the protective layer, and is sandwiching a gap region with the passivation layer and the protective layer in a first direction along the second surface. The collecting electrode includes an electrode layer located on the protective layer, a first connecting portion located in the gap region and connecting the electrode layer and the second surface, and a second connecting portion penetrating the passivation layer and the protective layer and connecting the electrode layer and the second surface in a second gap, and is electrically connected with the bus bar electrode.
