AI总结:

提出基于品质因数的框架评估光伏材料,纳入经典方法未涵盖的效率限制,计算多种光伏吸收体的效率限制,揭示早期吸收体未来效率潜力差异,该因数可用于闭环研究及搭建材料特性与效率的定量桥梁。

摘要:

我提出了一个通用的定量框架,用于评估实验室制造和计算机模拟的任何发展水平的光伏吸收体的质量、追踪其历史发展并指导未来优化。该框架围绕一个光伏品质因数构建,旨在纳入经典详细平衡方法未涵盖的效率限制。为28种实验合成的光伏吸收体和10种计算机模拟的光伏吸收体计算了一组更严格的品质因数驱动的效率限制。分析显示早期吸收体未来实现高光伏效率的可能性差异很大。该品质因数可即时由单个方程评估,适合自主实验室中光伏材料的闭环研究,还能在计算确定的材料特性和光伏效率之间提供定量桥梁。

英文摘要:

I propose a general quantitative framework to evaluate the quality, track the historical development, and guide future optimization of photovoltaic (PV) absorbers at any development level, both lab-made and computer-simulated. The framework is centered around a PV figure of merit designed to include efficiency limitations that are not captured by classic detailed balance methods derived from the Shockley-Queisser limit. A more stringent set of figure-of-merit-driven efficiency limits are calculated for 28 experimentally synthesized PV absorbers and 10 PV computationally modeled absorbers. Among early-stage absorbers, this analysis reveals very large differences in their likelihood of achieving high PV efficiencies in the future. Since the proposed figure of merit is instantly evaluated from a single equation, it can be a suitable objective function for closed-loop research on PV materials in autonomous labs, while also providing a quantitative bridge between computationally determined material properties and PV efficiency.
