    • A solar cell is discussed. The solar cell includes a substrate having a first conductivity type and made of a crystalline semiconductor; an emitter region having a second conductivity type opposite the first conductivity type, and forming a p-n junction with the substrate; a surface field region having the first conductivity type and being separated from the emitter region; a first electrode connected to the emitter region; and a second electrode connected to the surface field region, wherein at least one of the emitter region and the surface field region includes a plurality of semiconductor portions, and at least one of the plurality of semiconductor portion is a crystalline semiconductor portion.
    • 讨论太阳能电池。 太阳能电池包括具有第一导电类型并由结晶半导体制成的衬底; 具有与第一导电类型相反的第二导电类型的发射极区域,并与衬底形成p-n结; 具有第一导电类型并与发射极区分离的表面场区; 连接到所述发射极区域的第一电极; 以及连接到所述表面场区域的第二电极,其中所述发射极区域和所述表面场区域中的至少一个包括多个半导体部分,并且所述多个半导体部分中的至少一个是晶体半导体部分。
