太阳能电池及其制造方法
摘要：
一种太阳能电池及其制造方法，包含一晶体硅半导体基板、一本质非晶硅半导体层、一非晶硅半导体层以及一透明导电层。所述晶体硅半导体基板具有一第一型掺杂，且所述晶体硅半导体基板上设有至少一沟槽，形成一封闭图形，封闭图形内定义为一第一电极区域，封闭图形外定义为一第二电极区域。其中本质非晶硅半导体层、非晶硅半导体层与透明导电层依序形成于晶体硅半导体基板上以及沟槽内，所述本质非晶硅半导体层、非晶硅半导体层与透明导电层于沟槽处会形成不连续的结构，并于第一与第二电极区域之间产生绝缘效果。
摘要（英）：

The present invention discloses a solar cell and a manufacturing method thereof. The solar cell includes a crystalline silicon semiconductor substrate, an intrinsic amorphous silicon semiconductor layer, an amorphous silicon semiconductor layer and a transparent conductive layer. The crystalline silicon semiconductor substrate possesses a first doped type and a trench is formed thereon to form an enclosed area to define a first electrode region in the enclosed area and a second electrode region out of the enclosed area. The intrinsic amorphous silicon semiconductor layer, the amorphous silicon semiconductor layer and the transparent conductive layer are formed sequentially on the crystalline silicon semiconductor substrate and in the trench. Having discontinuity in the trench, the amorphous silicon semiconductor layer, the amorphous silicon semiconductor layer and the transparent conductive layer provide an isolation function between the previously defined first and second electrode regions.
