あった。Concentrating solar cells generally use a Fresnel lens as a concentrating lens.1. -It has a structure in which cells are placed near its focal point. FIG. 1 schematically shows the structure of such a conventional concentrating solar cell. The size of the cell used is about 1011111ψ to 40511ψ, and the lens often has an aperture of about 20011111ψ to 600 m+1ψ depending on the condensing ratio and the size of the cell. In conventional concentrating solar cells as shown in Figure 1, the focal length of the lens is relatively large, so
When the lens holder and the cell 14 are assembled, the overall size is large and bulky, and due to its structure, the lens support (12'
, cell support stand, 14, and other mechanical parts ψ must be assembled, resulting in a drawback that a large number of assembly steps are required.

施例について詳しく説明する。The present invention improves the shortcomings of conventional concentrating solar cells as described above, and provides a thin, robust, and easy-to-assemble concentrating solar cell panel that is integrally formed into a flat plate. The feature is that concentrating solar cells with cells 5 arranged and fixed near the focal point of a small lens are integrated and arranged in an array.'The present invention will be explained in detail below with reference to the drawings. .

着されている。FIG. 2 shows a cross-sectional view of an example of the concentrating solar cell panel of the present invention. A small lens 22 is arranged and fixed to each of the solar cell chips 21 having a cut angle of about 1. The solar cell chip 21 is, for example, a high-efficiency GaAJA for condensing light.
s/Qa A S and these chips are mounted on a lower substrate 28 consisting of an alumite plate with a printed wiring pattern. The small lens 22 is molded from a transparent resin with a high refractive index, and is integrally formed and fixed on the lower base 23 so that the solar cell chip 1 is located near its focal point.

量産に適するという集光式太陽電池としては従来前えら
れなかった著しい特徴を有している。The above-mentioned concentrating solar cell panel has the following features: (1) The size of the solar cell chip l is about 1 cm, which is smaller than a general solar cell, so it is possible to use a concentrating lens! The size of the light source only needs to be as small as lOI+II+I~zomm, and therefore the overall thickness can be made small and thin despite being a highly condensing type. (2) It is robust because the lower base 23 and the upper transparent base 25 are integrally fixed via the spacer 24. (3) It has a simple structure and is suitable for mass production, which is a remarkable feature that has never been seen before as a concentrating solar cell.

By designing an appropriate shape and refractive index, it can be used not only when sunlight is incident perpendicularly, but also when it is incident obliquely.
It is possible to focus on the solar cell chip. With such a configuration, sunlight can be effectively focused without a strict solar tracking mechanism, and the tracking mechanism can be simplified or omitted.
