摘要： PURPOSE:To form high performance modules in small size and compactness by expanding the effective areas of elements at both ends more than those of others, among solar battery elements in series connection. CONSTITUTION:The solar battery elements 20 at both ends are enlarged in the effective area by being lengthened by a+t more than the width l of the other elements 11. Where, the sign (a) represents the thickness of a case frame 12, and the sign (t) represents the width of a superposition part 13 of the frame 12 and the element 20. When the surface of the element is irradiated, the part of the width a+t is shielded. Since an actual light source is strong in directivity, the decrease of an output is alleviated more or less. However, the decrease of the output of these both end elements restrains the characteristic of the other elements, thus causing the decrease of the output. By this constitution, the decrease of the output is compensated by enlarging the effective area of the element 20 by (a+t), therefore the decrease of the performance of a module due to the shielding of incident light does not generate, and then a compact and high performance device can be obtained.

摘要： PURPOSE:To reduce a temperature rise by a method wherein when a solar battery element is housed in a metallic case and enclosed with transparent resin to make a battery, covering with a transparent resin plate or a glass plate, a nitrided boron layer is interposed between the element and the metallic case. CONSTITUTION:A silicon rubber sheet 5 for radiating heat is laid in a top-opened metallic case which is provided with radiating fins on the reverse side, and a solar battery element is arranged thereon. Then, a transparent silicon resin 3 is filled up within a case 1, and an opened end of the case 1 being a light receiving surface is covered with a cover 4 formed of a guard glass plate or a resin plate to make a battery. in this construction, a nitrided boron plate 6 is additionally interposed between the bottom surface of the case 1 and the rubber sheet 5. Thus, the difference between the temperature of the element 2 and that of the air becomes small and best suited for placing in the outdoor, due to insertion of the boron plate 6 having thermal conductivity as large as 160X10 cal/cm.sec. deg.C.

摘要： PURPOSE: To provide satisfactory adhesion strength between a CdS film and a metallic film by reducing a CdS surface chemically and by forming a metallic member thereon thereafter. CONSTITUTION: A CdS film 2 is formed on a glass substrate 1 as a CdS substrate used for joining a metallic member. Before a Cd film 4 is formed on the CdS film 2, the CdS film 2 is immersed in hydrazine solution in advance and a surface of the CdS film 2 is chemically reduced and a surface layer 3 is formed. Thereafter, it is cleaned in deoxidation ion exchange water and the one which is further cleaned by acetone is dried in inert atmosphere. The Cd film 4 is formed in a substrate obtained in this way by a resistance heating vacuum vapor deposition device and a CdS semiconductor electrode is prepared. Thereby, a CdS semiconductor electrode with enough adhesion strength can be produced between a semiconductor material and a metallic material.

摘要： PURPOSE:To realize a solar cell having a high efficiency by heat treating a thin film made of halogenated cadmium compound at a melting point or higher, and forming a CdTe film as a light absorption layer. CONSTITUTION:A CdS film 2 is deposited 1000Angstrom on a substrate 1 at an Ar partial pressure of 5X10 Torr, a board heating temperature of 30 deg.C, a CdCl2 film 3 is vapor-deposited 1000Angstrom on the surface, and treated at 600 deg.C under the atmospheric pressure in an Ar atmosphere. After CdTe paste made of Cd, Te, propylene glycol, etc., is printed, it is dried, and baked at 650 deg.C to form a CdTe film 4. By the similar method, a C film 5 and an Ag/In film 6 are sequentially formed by a screen printing method, and a solar cell is manufactured. Accordingly, even if the film 2 is reduced in thickness, formation of a CdTe1-ySy film can be prevented, and hence the cell having high optical sensitivity and high effective conversion efficiency can be obtained.

CONSTITUTION:In a battery comprising a gas diffusion electrode 1, in which oxygen is used as the active material, and a battery container having an air intake hole 3 communicated with the outside air, a perovskite type compound oxide thin film 11 at a thickness of 0.01-1.0mum, which is formed on a fine porous base material 4 having hole diameters less than 0.1mum, is interposed between the air intake side of the gas diffusion electrode 1 and the inner surface of the battery container. This compound material made of the perovskite type compound oxide thin film 11 has oxygen penetrability required for obtaining the sufficient discharge characteristic under the heavy load condition and transmission stopping power against steam and carbon dioxide for enduring long-term hot insulation and long-term discharge under the lower moisture or high moisture condition. Storage property of a battery, in which alkali aqueous solution and neutral salt aqueous solution are used as electrolyte, and performance in a long-term usage are thereby improved, and sufficient discharge performance under the wide discharge condition from light load to heavy load can be obtained.

摘要： PURPOSE:To improve the optical conversion efficiency of an amorphous silicon solar cell by making a substrate temperature at the time of the formation of an N-type amorphous silicon layer higher than that at the time of the formation of a P-type amorphous silicon layer and an I-type amorphous silicon layer. CONSTITUTION:A P-layer 3 and an I-layer 4 are formed at a substrate temperature of 130-150 deg.C which will not affect the film quality of the layers 3, 4. An N-layer 5 is formed at a higher substrate temperature, which is 50-100 deg.C above that for the formation of the layers 3 and 4 but may not affect the interfaces between a transparent electrode 2 and the P-layer 3 and between the P-layer 3 and the I-layer 4. Accordingly, the film quality of each layer and ohmic properties with electrodes are improved without deteriorating the interfaces between the transparent electrode 2 and the P-layer 3 and between the P-layer 3 and the I layer 4, thus enhancing a curve factor, then ameliorating photoelectric conversion efficiency.

摘要： PURPOSE:To patterning the transparent conductive film on the incident light side without using a resist by dipping and patterning only a first transparent conductive film in an etchant. CONSTITUTION:After depositing first an ITO (first transparent conductive film) 2 on a glass substrate 1 to a thickness of 2000Angstrom , a SnO2 (second transparent conductive film) 3 is deposited to a thickness of 200Angstrom . Then, using a knife edge (metal piece) of carbon steel as a scriber, the whole of the thickness of the deposited SnO2 film 3 and part of the thickness of the ITO film 2 are scribed off (4) with a predetermined pattern. Then, this is dipped in a strong hydrochrolic acid to remove the ITO film 2 left in the parts 4 of removal by the above scribing. Thereafter, an amorphous silicon (pi, n layer) 5 and an electrode 6 on the transmitted light side are formed in the respective predetermined patterns.
