Abstract: A monolithic solar battery including a plurality of P-N junction unit solar cells mounted on a substrate is provided. Each unit solar cell is isolated electrically from an adjacent cell by a buffer region of a material having a different conductivity than the substrate. An active photovoltaic layer formed on the light receiving surface of each solar cell between two buffer regions overlaps one of the two buffers defining each cell. Wiring for electrically connecting the unit solar cells in series fashion and electrodes are provided on the upper or lower surfaces of the substrate.
