Abstract Solar energy has become one of the most developed renewable energy sources in recent years. As with any energy source or product, there are health risks associated with the manufacturing of solar cells. And even though the photovoltaic industry uses far lesser amounts of toxic and flammable substances than many other industries, the use of hazardous chemicals can present occupational and environmental hazards. One of the most important aspects in the selection of new processes lies in the protection of workers’ health. Health risks can be reduced if a process is chosen properly and in preliminary phases. Since we have found that it is necessary to carry out an evaluation of the health risks to workers in the production of polycrystalline silicon for the manufacturing of photovoltaic cells, in this work we will use the Process Route Healthiness Index to quantify the health risk that each silicon production process represents (the higher the index, the higher the hazards). The polycrystalline silicon production processes evaluated with the healthiness index are: Siemens Process, Intensified Fluidized Bed Reactor Union Carbide Process, and Hybrid Process. Our results show that the Siemens Process is the healthiest process, but with the Process Route Healthiness Index values are closer to the Hybrid Process. Apart from this, a guide to the assessment of inherent occupational health hazards in SiSG production processes was also developed, which provides results alike those to the PHRI methodology.

太阳能级硅生产中的固有职业健康危害

摘要 太阳能已成为近年来最发达的可再生能源之一。与任何能源或产品一样，太阳能电池的制造也存在健康风险。尽管光伏行业使用的有毒和易燃物质比许多其他行业少得多，但使用危险化学品可能会带来职业和环境危害。选择新工艺的最重要方面之一在于保护工人的健康。如果在初步阶段正确选择流程，则可以降低健康风险。由于我们发现有必要对生产光伏电池的多晶硅生产工人的健康风险进行评估，在这项工作中，我们将使用工艺路线健康指数来量化每个硅生产工艺所代表的健康风险（指数越高，危害越大）。用健康指数评价的多晶硅生产工艺有：西门子工艺、强化流化床反应器联合碳化物工艺和混合工艺。我们的结果表明，西门子过程是最健康的过程，但过程路线健康指数值更接近混合过程。除此之外，还制定了评估 SiSG 生产过程中固有职业健康危害的指南，该指南提供了与 PHRI 方法类似的结果。用健康指数评价的多晶硅生产工艺有：西门子工艺、强化流化床反应器联合碳化物工艺和混合工艺。我们的结果表明，西门子过程是最健康的过程，但过程路径健康指数值更接近混合过程。除此之外，还制定了评估 SiSG 生产过程中固有职业健康危害的指南，该指南提供了与 PHRI 方法类似的结果。用健康指数评价的多晶硅生产工艺有：西门子工艺、强化流化床反应器联合碳化物工艺和混合工艺。我们的结果表明，西门子过程是最健康的过程，但过程路径健康指数值更接近混合过程。除此之外，还制定了评估 SiSG 生产过程中固有职业健康危害的指南，该指南提供了与 PHRI 方法类似的结果。但流程路线健康指数值更接近混合流程。除此之外，还制定了评估 SiSG 生产过程中固有职业健康危害的指南，该指南提供了与 PHRI 方法类似的结果。但流程路线健康指数值更接近混合流程。除此之外，还制定了评估 SiSG 生产过程中固有职业健康危害的指南，该指南提供了与 PHRI 方法类似的结果。
