用于太阳能电池的漫射外部光阱

Diffusive external light-trap for solar cells

Ido Frenkel, Shilpi Shital, Avi Niv

摘要:

吸收光的能力是高效太阳能发电不可或缺的。这对太阳能电池的结构提出了相互矛盾的要求:一方面,它需要有厚的活性层来吸收更多的可用阳光,而另一方面,它需要更薄的活性层来更好地传输电荷。这种困境阻碍了任何半导体实现其作为太阳能电池材料的全部潜力。最近,外部光阱已经成为一个具有成本效益的解决方案,通过能够解耦的光学从电池中的发电过程的电子方面的这种困境。本文研究了具有漫射内反射壁的外部光阱的有效性。结果表明,如果设计正确,外部光阱可能会为高效率、高成本效益的太阳能发电提供真正的机会。

英文摘要:

The ability to absorb light is indispensable for high efficient solar power generation. This places conflicting requirements on the structure of a solar cell: On one hand, it needs to have thick active layers to absorb more of the available sunlight while on the other it needs thinner ones for better charge transport. This dilemma stands in the way of any semiconductor from ever achieving its full potential as a solar cell material. Recently, external light-traps have emerged as a cost-effective solution for this dilemma by being able to decouple the optics from the electronic aspects of the power-generating process in the cell. In this paper, we study the effectiveness of external light-traps with diffusive inner reflecting walls. Results indicate that given the correct design, external light-traps may present a genuine opportunity for high-efficiency cost-effective solar power production.
