ASPIRE: Arctic solar photovoltaics: innovation for renewable energy

太阳能光伏能源技术在全球范围内建立并有效，特别是在高太阳能资源地区，主要是在固定倾斜单面硅光伏板装置中。在这些地区之外，商业采用率随着可用太阳能资源的减少而下降。 然而，在北极地区也有光生能源的情况：（1）由于夏季很长，太阳能资源与低纬度地区相似;（2）硅光生能源在较冷的温度下效率更高;（3）取代柴油燃料具有经济和环境优势。 备受关注的颠覆性技术生态系统是硅双面光伏面板。双面面板的正面和背面都接受阳光，但仅比单面面板稍微贵一点。这些电池板可以直接从太阳、天空、云层边缘、附近建筑物外墙或明亮的积雪地面收集能量。添加双轴跟踪器意味着电池板可以连续指向最佳方向，以在整个地平线上产生最大的太阳能。 传统的硅太阳能电池接近其实际性能极限，约17- 18%。采用金字塔形表面织构和非晶的新型先进双面硅电池|晶体异质结具有超过21%的效率的良好前景，并且将在跟踪器上设计、制造和现场测试。将建立用于设计支持和系统成品率预测的综合数值模型。ASPIRE的目标是使用先进的跟踪双面电池将北极地区固定倾斜单面电池的产量提高一倍。 这项建议是基于uOttawa SUNLAB的Karin Hinzer博士、亨利施里默博士和琼·海索姆博士、亚利桑那州立大学的Mariana Bertoni博士和育空地区学院的Michael Ross博士之间的长期合作。该项目将与加拿大高北极研究站（CHARS）、摩根太阳能公司（Morgan Solar Inc.）（追踪器）和Spectrafy Inc.（计量学）。

Solar photovoltaic energy technology is globally established and effective, especially in high solar resource regions, largely in fixed-tilt monofacial silicon photovoltaic panel installations. Outside these regions commercial adoption rates decline following the available solar resource. However, there is a case for photovoltaics in the Arctic: (1) the solar resource is similar to lower latitudes due to very long summer days; (2) silicon photovoltaics are more efficient in cooler temperatures; and (3) displacement of diesel fuel is an economic and environmental advantage. A disruptive technology ecosystem receiving much attention is silicon bifacial photovoltaic panels. Bifacial panels receive sunlight on both front and rear faces, but are only slightly more expensive than monofacial panels. These panels can harvest energy arriving direct from the sun, and from the sky and from cloud edges and from nearby building facades or bright snow-covered ground. Adding dual-axis trackers means the panels can be pointed continuously into the best orientation to generate maximum solar power, around the entire horizon. Conventional silicon solar cells are nearing their practicable performance limit, ~17-18%. Novel advanced bifacial silicon cells using pyramidal surface texturing and amorphous|crystalline heterojunctions hold good promise for efficiencies beyond 21% and will be designed, fabricated, and field tested on trackers. Comprehensive numerical models for design support and system yield forecasting will be established. The goal of ASPIRE is to double the yield of fixed-tilt monofacial in the Arctic using advanced tracked bifacial cells. This proposal is based on long-standing collaborations among Dr. Karin Hinzer, Dr. Henry Schriemer, and Dr. Joan Haysom of the uOttawa SUNLAB; Dr. Mariana Bertoni of Arizona State University; and Dr. Michael Ross of Yukon College. The project will partner with the Canadian High Arctic Research Station (CHARS), Morgan Solar Inc. (trackers) and Spectrafy Inc. (metrology).
