PURPOSE:To obtain a solar battery which can be operated by light irradiation from the front and back surfaces of a substrate by a method wherein a transparent conductive film, an amorphous Si layer having a P-I-N junction, an electrode layer, an amorphous Si layer having an N-I-P junction, and a transparent conductive film are provided in successive lamination on a transparent substrate. CONSTITUTION:After forming an ITO film 51 of the film thickness of 700Angstrom on the glass substrate 50, a P type 52, an I-type 53, and an N type amorphous Si layer 54 respectively of the thickness of 100Angstrom , 6,000Angstrom , and 100Angstrom are formed. Thereafter, an ITO film 55 of 1,200Angstrom is formed, further thereon an N type 56, an I-type 57, and a P type amorphous Si layer 58 respectively of the thickness of 100Angstrom , 5,000Angstrom and 100Angstrom are formed, and afterwards an ITO film 59 of 700Angstrom is formed. Thereby, the battery can be operated by irradiating it with light from both of the side of the glass substrate 50 and that of the ITO film 59. |
