Research Abstract

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.
