本文提出了一种适用于光伏发电的计费方案并加以应用。所采用的方案旨在克服EROI(能源投资回报)和EPBT(能源回收时间)等传统指标的局限性，并更全面地描述能源和物质的转变。建议的方法基于社会和生态系统代谢的多尺度综合分析(MuSIASEM)方法。在这项工作中，为了确定光伏发电系统的限制因素，提出了可持续发展的四个方面：能源和材料可获得性；环境健康合意性；技术可获得性；社会经济可接受性。在这四个维度的基础上，评估了基于晶体硅片电池的光伏电站对流动和资金要素(银、能量载体和水作为流动；人的时间和土地作为资金)的直接和间接需求，并讨论了现有光伏系统整体性能和局限性的影响。这些参数还与其他电力生产技术进行了比较，并与一个现代国家(西班牙)的能源和矿业部门的表现作了比较。得出的结论是，银的可用性可能会限制光伏电池的制造。此外，光伏设施的低功率密度可能会导致显著的土地热潮。最后，在筹资过程中分配的人力可能会严重制约现代社会新陈代谢的要求。(C)2016爱思唯尔有限公司。保留所有权利。
In this paper a photovoltaic (PV) technologies for electricity generation accounting scheme is proposed and applied. The adopted scheme aims to overcome limitations of conventional indicators such as EROI (Energy Return on Investment) and EPBT (Energy Payback Time) and to present a more comprehensive description of energy and material transformations. The proposed methodology is based on the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) approach. In this work, four dimensions of sustainability which should be addressed for the purpose of identifying the limiting factors of photovoltaic systems for electricity production are presented: Energy and Material Accessibility; Environmental Health Desirability; Technological Achievability; and Socioeconomic Acceptability. In relation to these four dimensions, the direct and indirect requirements of flow and fund elements (silver, energy carriers and water as flows; human time and land as funds) in photovoltaic power stations based on crystalline silicon wafer cells are evaluated and the implications of the overall performance and limitations of the present PV systems are discussed. These parameters are also compared with other electricity production technologies as well as benchmarked against the performance of the energy and mining sector of a modern country (Spain). It is concluded that the availability of silver could constrain photovoltaic cell manufacturing. Furthermore, the low power density of photovoltaic installations could drive a remarkable land rush. Finally, the human labor allocated in the fund making process could represent a serious constraint in respect to the requirements of the metabolism of modern societies. (C) 2016 Elsevier Ltd.
