PURPOSE:To enhance heat resistance of the solar cell, and moreover to enable irradiation of the rays of the sun having high energy density by a method wherein the photo receiving face of the solar cell is coated with a transparent and uniform oxide thin film generated by thermal decomposition of an esterified organic metal, while an isotropic graphite layer having favorable heat conductivity is adhered on the back surface. CONSTITUTION:A single layer oxide film 2 of SiO2, TiO2, Ta2O5, etc., or a mixed oxide film 3 of SiO2-TiO2 is adhered on the surface and on the back of the solar cell element 1 consisting of CdS, GaAs and GDa-Si, or formed with a P-N junction. Then the isotropic graphite layer 4 is adhered on the back on the layer 3 side to enhance heat radiability of the element 1, and holes 5 of the plural number are dug in the layer 4 if necessary holding in parallel with the element 1, and copper tubes or heat pipes are made to penetrate thereto. Accordingly, the ultraviolet rays intercepting type or the heat rays reflecting type thin film is provided on the surface of the element 1, while the heat radiating characteristic from the back surface is made also as favorable, and the element 1 is made to have high efficiency.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement of solar cells, and in particular, the light-receiving surface is coated with a transparent and uniform oxide thin film produced by thermal decomposition of an organic esterified metal to prevent thermal deterioration of the light-receiving surface. Alternatively, by integrally providing isotropic graphite with good thermal conductivity on the back side, the heat accumulated in the solar cell can be effectively dissipated, thereby increasing the heat resistance of the solar cell. The solar cell is made to be irradiated with sunlight with high energy density focused by a lens or the like, thereby making the solar cell smaller, less expensive, and more efficient.

It is composed of GaAs, GDa-Si, or P-N bonded Si, and the front and back surfaces of the solar cell element are coated with, for example, 5iOz, TiO2, or TazOs.
A single oxide thin film such as the above or a mixed oxide thin film 2 and 3 of 5iOz-TiOz is applied, and the back surface of the solar battery element 1 on which the oxide thin film is formed is as described above. Isotropic graphite 4 is integrally attached via an electrical insulating layer 3 formed as follows. In addition, although the above embodiment shows an example in which the surface protective coating 2 and the electrical insulation coating 3 on the back surface are simultaneously formed of the same material, the electrical insulation coating 3 is not limited to the above embodiment, Materials other than those mentioned above may be used as long as they can withstand the temperature and do not cause the current of the solar cell element 1 to leak toward the isotropic graphite 4. Also,
The protective coating 2 on the front surface prevents thermal deterioration of the light-receiving surface of the solar cell element 1, and the isotropic graphite 4 on the back surface improves heat dissipation of the solar cell element 1 and prevents a decrease in efficiency of the solar cell element. Therefore, these do not necessarily have to be used at the same time.

As the material for the oxide thin film, a material that passes the light component that acts most effectively on the solar cell element is used, or the oxide thin film is composed of multiple layers made of materials with different refractive indexes, and the desired It is preferable to allow only the light component to act on the solar cell element. The oxide thin film produced by thermally decomposing organic esterified metals in this way has much lower heat resistance than conventional coating thin films, and therefore cannot absorb high energy density sunlight focused by lenses etc. Therefore, it becomes possible to make solar cells smaller and more efficient, and to reduce the cost of solar cells.

Furthermore, as mentioned above, the solar cell according to the present invention can irradiate sunlight with high energy density, but naturally heat is generated when irradiated with sunlight with high energy density. Heat is generated by a high heat resistant device installed on the back side of the solar cell.
Heat is effectively dissipated by the isotropic graphite 4, which is a good thermal conductor, but in order to make this heat dissipation even more effective, holes 5 are made in the isotropic graphite 4 as shown in Fig. 2. If a steel pipe, a heat pipe, or the like is passed through the hole 5, heat can be effectively radiated through the steel pipe or heat pipe.
