Methods of forming semiconductor solar cells having front surface electrodes |
摘要 |
Solar cells include a substrate having a light collecting surface thereon and a P-N rectifying junction within the substrate. The P-N rectifying junction includes a base region of first conductivity type (e.g., p-type) and a semiconductor layer of second conductivity type extending between the base region and the light collecting surface. A trench is also provided, which extends through the semiconductor layer and into the base region. First and second electrodes are provided adjacent the light collecting surface. The first electrode is electrically coupled to the semiconductor layer and the second electrode is electrically coupled to the base region, at a location adjacent a bottom of the trench.
