PURPOSE: A solar battery and solar cell module comprise the optical waveguide layer on the peripheral region of supporter. The light is centered to the solar battery. CONSTITUTION: The light accepting body(110) comprises the first semiconductor region(112) of the first conductivity type and the second semiconductor area(115) of the second conductive type. The first semiconductor region and the second semiconductor area materially have the perpendicularity P-N junction(118) on substrate. The first semiconductor region comprises the first inner surface and the first exterior facing the first inner surface.
