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.

为了降低太阳光到电能的转换效率和降低生产成本，设计了一次光学元件和二次光学元件的新概念，用于轻薄聚光光伏系统组件。单片串联光伏电池也被开发用于减小电流和增加工作电压。这种串联连接的电池是用于高度阳光集中系统的合适的能量转换装置。此外，我们还开发了聚光光伏系统的试验小型模块，并在现场测试设备下进行了评估。
