The electricity generation device contains one or more photovoltaic members arranged into an array. Each photovoltaic member contains a solar cell and a reflection mirror. The solar cell is positioned above the reflection mirror with its light incidence plane facing downward towards the reflection mirror. The reflection mirror is formed by piecing a number of reflection plates side by side into a circular dish or by arranging a number of reflection dishes into a ring. The reflection plates or dishes are arranged so as to reflect the light beams towards the solar cell. The reflection mirror can also be an upside-down cone having slant inner surface or a dish having parabolic inner surface.
