论文摘要
新型的光伏技术,例如钙钛矿和钙钛矿启发的材料,由于效率高和潜在的制造成本较低而显示出巨大的希望。到目前为止,太阳能电池研发主要集中于实现创纪录的效率,这一过程通常会导致小批量,差异较大,并且对表现不佳的身体原因有限。这种方法在时间和资源上是密集的,并且忽略了工业生产的许多相关因素,尤其是对高可重复性和高生产产量的需求以及伴随的物理见解的需求。记录效率范式在早期研发中有效,但不适合工业翻译,需要在工业环境中重复进行优化程序。优化目标之间的这种不匹配,结合了物理根本原因分析的复杂性,促成了长达十年的时间表,以将新技术转移到市场上。基于最近的机器学习和技术经济进步,我们的观点阐明了一个数据驱动的优化框架,以桥接研发和制造优化方法。我们通过考虑两个附加维度来扩展最大效率优化范式:技术经济学图和可扩展的物理推断。我们的框架自然会使技术开发的不同阶段与共享优化目标保持一致,并通过提供物理见解来加速优化过程。
Novel photovoltaics, such as perovskites and perovskite-inspired materials, have shown great promise due to high efficiency and potentially low manufacturing cost. So far, solar cell R&D has mostly focused on achieving record efficiencies, a process that often results in small batches, large variance, and limited understanding of the physical causes of underperformance. This approach is intensive in time and resources, and ignores many relevant factors for industrial production, particularly the need for high reproducibility and high manufacturing yield, and the accompanying need of physical insights. The record-efficiency paradigm is effective in early-stage R&D, but becomes unsuitable for industrial translation, requiring a repetition of the optimization procedure in the industrial setting. This mismatch between optimization objectives, combined with the complexity of physical root-cause analysis, contributes to decade-long timelines to transfer new technologies into the market. Based on recent machine learning and technoeconomic advances, our perspective articulates a data-driven optimization framework to bridge R&D and manufacturing optimization approaches. We extend the maximum-efficiency optimization paradigm by considering two additional dimensions: a technoeconomic figure of merit and scalable physical inference. Our framework naturally aligns different stages of technology development with shared optimization objectives, and accelerates the optimization process by providing physical insights.
