论文摘要
在千年过渡期间，使用Stibnite（SB2S3）作为固态敏化太阳能电池中的敏化剂具有相当大的研究兴趣。然而，钙钛矿的使用减少了该领域的研究，并且没有彻底探索豆科裔葡萄染色剂（SB2（S，SE）3）的潜力。尽管这些材料还通过改变S和SE的组成来提供带隙的调谐，例如钙钛矿，但它不像钙钛矿那样流行，主要是因为基于它的太阳能电池的效率低。在本文中，我们介绍了各种设备参数在SB2（S，SE）3太阳能电池性能方面的功能作用的景观。为此，我们首先通过文献的实验结果校准用于仿真的光电模型。然后，将模型进行参数变化，以探索此类太阳能电池的性能指标。我们的结果表明，尽管人们相信开路电压独立于在适当的带对齐敏化的太阳能电池中掺杂的接触层，但我们在这里观察到否则，开路电压确实取决于接触层的掺杂密度。使用详细的数值模拟和分析模型，我们进一步确定了基于SB2（S，SE）3的敏化太阳能电池的性能优化图。
The use of stibnite (Sb2S3) as sensitizers in the solid-state sensitized solar cells received considerable research interest during the transition of the millennium. However, the use of perovskite diminished the research in the field and the potential of antimony chalcogenide (Sb2(S,Se)3) was not explored thoroughly. Although these materials also provide bandgap tuning like perovskite by varying the composition of S and Se, it is not as popular as perovskite mainly because of the low efficiency of the solar cells based on it. In this paper, we present a landscape of the functional role of various device parameters on the performance of Sb2(S,Se)3 based solar cells. For the purpose, we first calibrate the optoelectronic model used for the simulation with the experimental results from the literature. The model is then subjected to parametric variations to explore the performance metrics for this class of solar cells. Our results show that despite the belief that open circuit voltage is independent of contact layers doping in proper band aligned sensitized solar cells, here we observe otherwise and the open circuit voltage is indeed dependent on the doping density of the contact layers. Using the detailed numerical simulation and analytical model we further identify the performance optimization map of Sb2(S,Se)3 based sensitized solar cells.
