摘要

氢化工艺可以改善不同原料的硅(Si)太阳能电池的电性能,包括低成本原料,如升级的冶金硅(UMG-Si)。光伏技术的发展应辅之以生产过程的环境分析。在这里,我们对硅太阳能组件进行了环境分析,包括通过生命周期评估(LCA)方法添加氢化过程。据作者所知,LCA尚未应用于硅技术,如氢化。考虑到本LCA中所做的假设,我们表明加氢方法会产生更好的环境结果。

Life Cycle Assessment on Hydrogenation Processes on Silicon Solar Modules
Hydrogenation processes can offer improvements to the electrical performance of silicon (Si) solar cells from different feedstocks, including low-cost feedstocks, such as upgraded metallurgical silicon (UMG-Si). The development of PV technologies should be complemented by environmental analyses of the production processes. Here we undertake an environmental analysis of Si solar modules including the addition of hydrogenation processes through the life cycle assessment (LCA) method. LCA has not been applied to Si technologies such as hydrogenation, to the best of authors' knowledge. We show that the hydrogenation methods result in better environmental outcomes, considering the assumptions made in this LCA.
