Abstract
Attention is paid to reduction in area required for solar cells by solar concentration as a means of solving cost limits of solar cells and unstable supply of Si materials. Low concentration solar cells are effective from the aspects of utilization of scattered light and unnecessary ray tracing. The optical concentration ratio was calculated of three-dimensional lens having design values of various north/south and east/west direction allowable incidence half angles. The three-dimensional lens are designed by cutting a rectangular parallelepiped by the two-dimensional composite elliptical plane designed by various allowable incidence half angles from two directions of north/south and east/west. Using Perez`s sky solar radiation models and meteorological data HASP, calculated were the annual accumulated global radiation ratio on an inclined surface and the optical efficiency. Calculated were the solar cell area ratio and solar concentration area ratio of the concentration type to obtain solar radiation the same as that of the planar type. From the optimization calculation, it was found that lens are optimal which have design values of north/south and east/west direction allowable incidence half angles of 30-70deg. The solar cell area ratio is 57% and the solar concentration area ratio is 1.2 times. It was found that
