Outline of Final Research Achievements

We have developed a novel concentrator photovoltaic architecture harvesting not only direct sunlight but also diffuse sunlight, which cannot be harvested in the conventional concentration photovoltaic module. First, diffuse sunlight characteristics were observed and analyzed by using a sky scanning device. Second, based on the obtained diffuse sunlight characteristics, concentrator optics were designed and optimized, then the prototype mini-module was fabricated to conduct an outdoor test. As a result, the present mini-module achieved higher module conversion efficiency than the conventional concentrator photovoltaic module by facter of over 1.5. Furthermore, as a solution in order to reduce the cost of the module and the system, we investigated the potential of applying the present concept to a mechanical stack III-V/Si solar cell with low solar concentration. The result indicated the feasibility of the proposed solution.
