有几种方法通过电压损失来评估太阳能电池的性能。然而，每种方法的优点和缺点还没有被彻底讨论或阐明。本研究比较了这些不同的方法，以澄清其优点和缺点。带隙偏移WOC已用于评估电压损耗。然而，人们发现，这种方法给出了不准确的评估的电压损失，在薄体和量子结构的太阳能电池。我们的研究讨论了这种不准确的原因，并证明，我们可以准确地评估量子结构太阳能电池的非辐射电压损耗使用光电互易定理和详细平衡理论。我们的研究结果使太阳能电池的非辐射电压损失的公平，准确，方便的评估，促进了高效量子结构太阳能电池的发展。
There are several methods for the evaluation of the performance of solar cells through the voltage loss. However, the advantages and disadvantages of each method have not been thoroughly discussed nor elucidated. This study compares these various methods to clarify their advantages and disadvantages. The bandgap offset WOChas been used for the evaluation of the voltage loss. However, it was found that such approach gives inaccurate assessment of the voltage loss in thin-bulk and quantum-structure solar cells. Our study discusses the reasons for such inaccuracy and proves that we can accurately evaluate the nonradiative voltage loss in quantum-structure solar cells using the optoelectronic reciprocity theorem and detailed-balance theory. Our findings enable a fair, accurate, and accessible evaluation of the nonradiative voltage loss in solar cells which facilitates the development of high-efficiency quantum-structure solar cell.
