美国SolarWindow Technologies公司推出了名为ElectroFlex的超薄柔性太阳能薄膜产品1。该产品厚度仅为0.85毫米,采用自粘设计,可直接贴附于各种平面和曲面1。
ElectroFlex产品采用五层复合结构,包括0.10毫米前封装层、0.16毫米高效太阳能电池、0.04毫米铜背层、0.30毫米复合层和0.25毫米后基层1。该薄膜集成了背接触(IBC)太阳能电池,转换效率达24.4%,功率密度约为73瓦/千克1。
目前该产品仅向美国的一级设备制造商供应,计划在未来几个季度拓展至北美和亚洲市场1。该薄膜可应用于运输、船舶、航空航天、建筑、农业、基础设施、公用事业和特种车辆等领域,具体应用场景包括数据中心、商用卡车和车队屋顶、弯曲列车表面、无人机和飞机结构等1。
SolarWindow Technologies has introduced ElectroFlex, a commercially available flexible solar film measuring just 0.85 millimeters thick and featuring a self-adhesive design that can be applied directly to flat and curved surfaces 1. The product integrates back-contact solar cells with a conversion efficiency of 24.4% and delivers a power density of approximately 73 watts per kilogram 1.
The ElectroFlex film consists of a five-layer composite structure comprising a 0.10-millimeter front encapsulation layer, a 0.16-millimeter high-efficiency solar cell layer, a 0.04-millimeter copper backing layer, a 0.30-millimeter composite layer, and a 0.25-millimeter rear substrate layer 1. Currently, the product is supplied exclusively to Tier 1 equipment manufacturers in the United States, with plans to expand distribution to North America and Asia in the coming quarters 1.
The company targets applications across transportation, maritime, aerospace, building, agriculture, infrastructure, utilities, and specialty vehicles, with potential use cases including data center roofs, commercial truck and fleet rooftops, curved train surfaces, unmanned aircraft, and aircraft structures 1.
