ETFE cushion integrated transparent solar cell (EC-TSC) systems have gained more attention in recent years due to their lightweight structure, reduced material consumption, and renewable energy production. In this study, innovative EC-TSC systems are applied as the skylight for the atrium of a commercial building to replace the current PV glazing skylight. The environmental and economic sustainability of EC-TSC systems is investigated by applying life cycle assessment (LCA) and life cycle cost analysis (LCCA) in a cradle-to-cradle approach. LCA provides cumulative energy and greenhouse gas emissions to quantify environmental performance. LCCA considers the contribution of life cycle costs, building owner income, and social and environmental benefits to demonstrate economic viability and evaluate financial performance. A novel distributed allocation method is proposed to illustrate the impacts of recycling benefits across all life cycles. The results are compared with those of the previous PV glazing skylight. From the results, EC-TSC systems are shown to be more cost-effective and environmentally friendly than PV glazing skylights, provided the commercial product can realize the prospective physical characteristics. This paper demonstrates the significant potential of EC-TSC systems for building retrofitting in terms of economic and environmental performance, representing an important step toward supporting the transition of BIPVs to environmental and economic sustainability.

ETFE缓冲集成透明有机/钙钛矿太阳能电池的生命周期成本分析和生命周期评估：与PV玻璃天窗的比较

ETFE缓冲集成透明太阳能电池（EC-TSC）系统近年来因其轻质结构、减少材料消耗和可再生能源生产而受到越来越多的关注。在本研究中，创新的 EC-TSC 系统被应用于商业建筑中庭的天窗，以取代当前的光伏玻璃天窗。通过在从摇篮到摇篮的方法中应用生命周期评估 (LCA) 和生命周期成本分析 (LCCA)，研究 EC-TSC 系统的环境和经济可持续性。 LCA 提供累计能源和温室气体排放量来量化环境绩效。 LCCA 考虑生命周期成本、建筑业主收入以及社会和环境效益的贡献，以证明经济可行性并评估财务绩效。提出了一种新颖的分布式分配方法来说明回收效益对所有生命周期的影响。结果与之前的光伏玻璃天窗的结果进行了比较。结果表明，只要商业产品能够实现预期的物理特性，EC-TSC 系统比光伏玻璃天窗更具成本效益和环保性。本文展示了 EC-TSC 系统在经济和环境绩效方面用于建筑改造的巨大潜力，代表着支持 BIPV 向环境和经济可持续性转型的重要一步。
