Solar cell

The utility model provides a solar cell, including at least a set of solar cell unit, the every solar cell of group unit includes: first substrate, this first substrate is flexible substrate, in proper order the deposit in back electrode layer on the first substrate, cell layer, front electrode layer to reach the electrode lead who connects back electrode layer and front electrode layer respectively, solar cell still includes cylindricality second substrate, the not deposit face of first substrate pass through the binder adhesion in on the cylindricality second substrate. The utility model discloses compare present directness becomes the film preparation on the column substrate solar cell, preparation technology is simple, to equipment portion require low, the product preparation is with low costs. 本实用新型提供了种太阳能电池，包括至少组太阳能电池单元，每组太阳能电池单元包括：第衬底，该第衬底为柔性衬底；依次沉积于所述第衬底上的背电极层、电池层、前电极层，以及分别连接背电极层和前电极层的电极引线；所述太阳能电池还包括柱形第二衬底，所述第衬底的未沉积面通过粘结剂粘附于所述柱形第二衬底上。本实用新型相比现有的直接在柱状衬底上成膜制备的太阳能电池，制备工艺简单、对设备部要求低、产品制备成本低。
