Development of the high efficiency thin-concentrator photovoltaic systems

为降低生产成本，提高光能转化为电能的效率，设计了薄型轻量化聚光光伏系统组件主、次光学元件的新概念。为了减小电流和提高工作电压，还开发了单片串联光伏电池。这种串联电池是适合于高度太阳光集中系统的能量转换装置。在此基础上，研制了聚光光伏系统的试验性微型模块，并在现场测试设备下进行了评估。

Aiming for reducing the production cost and increasing conversion efficiency from sunlight to electric power, novel concept of primary and secondary optical element was designed for thin- and light-weight concentrator photovoltaic system module. The monolithic series connected photovoltaic cell had also been developed for reduced current and increased operation voltage. Such a series connected cell is the suitable energy conversion device for highly sunlight concentrated systems. Furthermore, we developed the trial mini-module of concentrator photovoltaic system and evaluated under field testing equipment.
