中间波段太阳能电池（IBSC）是一种具有吸引力但具有挑战性的高效太阳能转换技术，其理论效率极限为63%，但迄今为止未能在实践中产生高效率。最先进的IBSC技术是基于量子点（QDs）的：QD - IBSC。本文将量子点中光子吸收的k·p计算与多层详细平衡模型相结合。该模型已被用于再现实际QD - IBSC的测量量子效率及其温度依赖性。这允许对单个亚带隙跃迁电流进行分析，这在实验上是不可能的，从而对电流QD - ibsc的失效有了更深入的了解。基于与实验数据的一致，该模型被认为是现实的，足以评估未来的QD - IBSC提议。
An attractive but challenging technology for high efficiency solar energy conversion is the intermediate band solar cell (IBSC), whose theoretical efficiency limit is 63%, yet which has so far failed to yield high efficiencies in practice. The most advanced IBSC technology is that based on quantum dots (QDs): the QD‐IBSC. In this paper, k·p calculations of photon absorption in the QDs are combined with a multi‐level detailed balance model. The model has been used to reproduce the measured quantum efficiency of a real QD‐IBSC and its temperature dependence. This allows the analysis of individual sub‐bandgap transition currents, which has as yet not been possible experimentally, yielding a deeper understanding of the failure of current QD‐IBSCs. Based on the agreement with experimental data, the model is believed to be realistic enough to evaluate future QD‐IBSC proposals.
