在建筑照明的光伏应用中,聚光器是建筑照明光伏产业的核心,它决定着整个光伏能源在建筑照明工程中应用的造价。在对光伏能源产业施工过程中,合理利用光照强度、单位面积太阳能电池的成本及转换效率,决定着光伏能源的发电成本造价。本文通过在光伏能源施工过程中,改进CPC聚光器接收角,扩大接收范围内的入射光,接收直射太阳光和部分散射太阳光,在聚光器底部放置封装光伏电池真空管,接收太阳周围辐射,大幅度降低了应用造价。实验证明,改进型聚光器能够提高光伏产业的发电能力,降低造价成本,在光伏能源产业施工建设过程中有较大的推广价值。
In architectural lighting PV applications, concentrator is the core of architectural lighting photovoltaic industry, which determines the cost of the entire photovoltaic energy in the construction of lighting projects. In the construction of photovoltaic energy industry, the rational use of light intensity, the cost per unit area of solar cells and conversion efficiency, determines the cost of photovoltaic energy generation costs. In this paper, during the construction of photovoltaic energy, CPC receiver angle is improved, the incident light in the receiving range is expanded, direct sunlight and partially scattered sunlight are received, the vacuum tube of the photovoltaic cell is placed at the bottom of the condenser to receive the radiation around the sun , A substantial reduction in application costs. Experiments show that the improved concentrator can increase the photovoltaic power generation capacity and reduce the cost of the photovoltaic power industry in the construction process has a greater promotional value.
