摘要

本文报道了最近两个独立证实的硅太阳能电池效率的结果。据报道,单个硅电池的效率提高了24.5%,是有史以来最高的,多晶硅电池的效率提高了19.8%,后者比之前的最佳结果相对提高了6.5%。对于这种质量相对较低的材料,后一种结果不仅接近20%的效率标志,这一度被认为是硅电池性能的极限,而不管多晶硅材料的质量如何,而且还显示了这种多晶硅材料超过标准晶体Czochralski材料性能容量的潜力。

Recent progress in silicon solar cells
The present paper reports two recent independently confirmed results for silicon solar cell efficiency. An improved efficiency for an individual silicon cell of 24.5% is reported, the highest ever, as is 19.8% efficiency for a multicrystalline silicon cell, the latter representing a 6.5% relative improvement over the previously best result. Not only does the latter result for this relatively low quality material closely approach the 20% efficiency mark, once thought to be a limit on silicon cell performance regardless of multicrystalline material quality, but it also shows the potential for such multicrystalline material exceeding the performance capacity of standard crystalline Czochralski material.
