PROBLEM TO BE SOLVED: To provide a solar battery having both functions of effectively capturing light with a wavelength usable in the solar battery and reflecting infrared ray causing a temperature rise of the solar battery, among light entering the solar battery, without adversely affecting economic efficiency and productivity.SOLUTION: A solar battery includes a first electrode 2 comprising a light transmitting conductive material on a light receiving surface side of a photoelectric conversion layer 3. The first electrode 2 is formed by alternately laminating a plurality layers of first light transmitting conductive films 21 with a low carrier concentration and a plurality layers of second light transmitting conductive films 22 with a high carrier concentration. Accordingly, while a laminated film of the light transmitting conductive films functions as an electrode on a light receiving surface side of a solar battery cell, an infrared reflection effect can be obtained by utilizing the refractive index difference between the first light transmitting conductive films 21 and the second light transmitting conductive films 22 in an infrared region. |
