Abstract
Description
【発明の詳細な説明】 本発明は太陽電池電源装置の構造に関するものである。[Detailed description of the invention] The present invention relates to the structure of a solar cell power supply device.
一般に太陽電池は光を電気に変換する装置のことを云わ
れているが、実際に太陽電池の発電に寄与する元の波長
は、シリコン系で４００〜１２００ｎｍであシ・アモル
ファスの場合ハ４００〜８００ｎｍである。従って自然
太陽光の一部の光のみしか発電に寄与していない。この
ために、最近は九と太陽熱エネルギーを共に利用した太
陽電池が開発されつつある。Generally, solar cells are referred to as devices that convert light into electricity, but the original wavelength that actually contributes to power generation in solar cells is 400 to 1,200 nm for silicon-based materials, and 400 to 1,200 nm for amorphous materials. It is 800 nm. Therefore, only a portion of natural sunlight contributes to power generation. For this reason, solar cells that utilize both solar energy and solar thermal energy have recently been developed.
従来、この種の類似の電源装置としては、集光鏡もしく
は、フレネルレンズによシ集光された元を太陽電池素子
を取付けた熱コレクターに照射し発電する方式がある。Conventionally, as a similar power supply device of this kind, there is a method of generating electricity by irradiating light focused by a condensing mirror or a Fresnel lens onto a heat collector equipped with a solar cell element.
しかしながら太陽電池素子の温度上昇によシ性能が劣化
するため、集光度を大きくすることが難しいし、５０倍

かし太陽電池素子の温度上昇を避けるために、大損シな
冷却装置が必要でちるばかシか、実現出来ても冷媒体に
吸収するエネルギーの効率が悪く、エネルギーとして利
用することが難しい。However, since the performance of the solar cell element deteriorates due to an increase in the temperature of the solar cell element, it is difficult to increase the light concentration, and with a light concentration ratio of 50 times, the temperature increase required as a heat collector cannot be obtained. Therefore, a reflector or Fresnel lens with a condensing ratio of several thousand times is required as a heat collector. However, in order to avoid a rise in the temperature of the solar cell element, a cooling device with large losses is required, or even if it can be realized, the efficiency of the energy absorbed by the cooling medium is poor, making it difficult to use it as energy.
本発明の目的はかかる欠点を解消し、発電効率の高い太
陽電池電源を提供するにある。An object of the present invention is to eliminate such drawbacks and provide a solar cell power source with high power generation efficiency.
次に本発明の実施例を第１図に沿って説明すると、７レ

透過率を持つ接着材で下面に取付けられる。熱コレクタ
−４はフレネルレンズ１の焦点位置に置かれ照射面積以
外は断熱材（図示せず）に覆われている。Next, an embodiment of the present invention will be described with reference to FIG.
are connected in series and parallel by an interconnector (not shown), have the same refractive index as the Fresnel lens 1, and are attached to the lower surface with an adhesive having high light transmittance. The heat collector 4 is placed at the focal point of the Fresnel lens 1, and the area other than the irradiated area is covered with a heat insulating material (not shown).
次に本装置の動作を説明すると、太陽光５ａ〜５ｅがフ
レネルレンズｌを透過し、一部は太陽電池素子に吸収し
て発電に寄与し、一部は透過し、熱コレクタに集光され
る。例えば光線５ａ、５ｂ。Next, to explain the operation of this device, sunlight 5a to 5e passes through the Fresnel lens l, some of it is absorbed by the solar cell element and contributes to power generation, and some of it is transmitted and concentrated on the heat collector. Ru. For example, rays 5a and 5b.
５ｄは太陽電池素子以外の部分を直接透過し殆んど熱コ
レクタ−１に吸収する。またｊｔ線５Ｃ１５６のような
光は１２００ｎｍ以上の波長の光は太陽電池素子をシリ
コーンの板厚’ｋ Ｏ，３ｍｍ以下にすれば９８％以上
透過し熱コレクタ−１に吸収する。5d directly passes through parts other than the solar cell element and is almost absorbed by the heat collector 1. Furthermore, light having a wavelength of 1200 nm or more, such as the JT line 5C156, is transmitted by more than 98% and absorbed by the heat collector 1 if the silicone plate thickness of the solar cell element is set to 3 mm or less.
従って熱源となる赤及び赤外光の殆んどは熱コレクタ−
１に吸収される。熱コレクタ−１には従来の方法のよう
に、太陽電池素子を冷却する機能を必要としないため、
断熱材の効果によシ、よシ効率を上げることが出来るし
、太陽電池素子は従来の太陽電池（卵巣元型）と同等の
温度上昇であ広太陽電池の効率を下げることはない。Therefore, most of the red and infrared light that becomes a heat source is a heat collector.
1 is absorbed. Since the heat collector 1 does not require a function to cool the solar cell element as in the conventional method,
The efficiency of the solar cell can be greatly increased due to the effect of the heat insulating material, and the temperature rise of the solar cell element is the same as that of a conventional solar cell (ovarian type), so the efficiency of the Hiro solar cell will not be reduced.
また太陽電池素子を薄膜化もしくはアモザフ・Ｔス太陽
電池素子を適用すれば透過光による元エネルギーを熱コ
レクターによシ吸収出来るため、その効果が大きい。Furthermore, if the solar cell element is made thinner or an Amozaf-TS solar cell element is applied, the original energy from the transmitted light can be absorbed by the heat collector, which is highly effective.
