为提高太阳能利用率,提出了同时使用视日跟踪和光电跟踪的太阳跟踪新方法.为提高视日跟踪精度,对常见的太阳位置算法仿真比较,得到实用的太阳位置高精度混合算法；同时,设计了特制的四象限硅光电池,对视日跟踪进行误差修正,从而实现了太阳精确跟踪.理论分析和设计表明,该方法能够实现高精度、全天候地自动跟踪太阳,易于推广应用.%A new method based on simultaneous use of sun angle tracking and photo electric tracking is proposed in order to improve the utilization rate of solar energy. By the comparison of,some common sun tracking algorithms simulation ,a mixed practical high accuracy algorithm is proposed. A special four-quadrant solar cell is designed to dorrect the error of sun angle tracking so that the sun can be tracked precisely. Theory analysis and design show that the method could track the sun all-weather automatically and accurately , which has a wide spread applications.
