Outline of Final Research Achievements

As a method of increasing electric power generation in a size-limited installation area, photovoltaic modules assembled with a three-dimensional structure that is based on the Fibonacci number (FPM) have proven effective. We have proposed mega-solar sized power generation forests using the multiple FPMs. The generation forests electric characteristics have been studied by the computer simulation by using a projection method and the field test using single crystalline silicon solar cells. It is shown that the amount of a single FPM power generation decreases with the number of series cell connections and is little depended on phyllotaxis patterns. It is also shown that the honeycomb pattern FPM forest provides the largest amount of generated power per unit area.
