Description

200933777 六、發明說明: 【發明所屬之技術領域】 本發明係關於一種被設計成用於測試光 疋晃面板内所含的 電池效率之裝置的領域。更特別地,本發明係關於—種被抓 計成用於聚集光電面板的裝置之領域,也 Λ仏坑疋說,在此光電 面板上的光電電池較小,且藉由元件使光線集中於此光電面 板上,而這些元件例如可以是放置於電池前方的透鏡或鏡 子。通常是1GG到1_倍的集中。對於—個相等的電力來 說’如此能允許製造太陽能電池所使用的材料量得以減*相 同的比例。 【先前技術】 測試這類裝置的功能具有好幾項特別的困難點,其中一項 最值得注意的就是:光線必須垂直地,在幾度之内,到達每 個電池上,以便能夠複製出平行的太陽光線。在此測試裝置 中,光源顯然是人造的,且所發出的光線會分散。為了取得 平行性,習知的解決方案中利用拋物線的鏡子,其特性為能 夠精確地使來自焦點的分散光線變成平行。然而,製造出多 個大型拋物線鏡子是一項很困難的操作。 根據先前技術’沒有辦法個別地調整照射於每個電池上的 光線之參數。 而且,為了防止指定其中一個電池的光線到達另一個電池 上,通常使用的技術是藉由一根管子或通道而將指定每個電 097147605 4 200933777 池的光束隔開。利用此種方法意味著必須設有很多管子,其 數量等於欲測試的電池數量。由於這些管子必須相當長,所 以其數量勢必導致裝置重量的顯著增加。 【發明内容】 本發明之目的是要提供一種用於測試含有幾個不同的光 電電池之光電面板功能的裝置,即使光束是由單一焦點發 出’仍可使實質上平行的光束被導引於每個電池上’而且不 ❹需要建立一個大型的拋物線鏡子便可達到此效果。 而且’本發明亦打算允許個別地調整每個電池上所照射的 光線之強度與方向。 本發明亦打算提供一種裝置,其能防止指定 一個電池的光 線到達另一個電池上,且不需要求助於管子或通道。 圖式係以範例方式顯示本發明的兩個實施例。 【實施方式】 ❿本發明裝置的特點係界定於φ請專利範圍内。 本發明的裝置包含一個光源1及多個鏡子2。鏡子係固定 於轴6上’而軸本身被固定於支架3上。鏡子2係沿著一條 '實質上為拋物線的曲線而排列。光源1所發出的光線9照射 於鏡子2上’這些鏡子將光線10引導至固定在面板上的光 电電池4。由於鏡子2以拋物線方式排列,因此反射的光線 10疋以實質上平行的方式被引導至光電電池。每個鏡子均 指派至一個電池上。 097147605 5 200933777 鏡子被安裝於其軸6上,以允許這些鏡子得以被定向,藉 此能夠細微地調整其定向。 而且,軸6被安裝於支架3上’以便能夠在兩個方向上滑 動’如雙箭頭5所示在欲被照射的電池方向上。因此,使用 者可以調整鏡子與電池之間隔開的距離,藉此細微地調整照 射於電池上的光線強度。在此,並未顯示一個用於將鏡子2 與轴6限制在選定位置上的機構,可以使用任何習知的系 統’例如鎖緊螺釘。 理想地’每個鏡子應該是一條拋物線的曲線,其對應於安 放鏡子所沿著的拋物線。理論上,以此方式,光線1〇將會 恰好平行。 雖然在技術上製造並安裝一連串此種小型拋物線鏡子是 可能的,但仍需花費相當長的時間,因此代價昂貴。實際上, 最好利用一連串平坦的鏡子。自然地,在該情形下,只有被 每個鏡子中央部位所反射的光線10會真正平行。來自非中 央區域的光線10勢必會分散。然而,此光線分散並未大到 真正能夠影響測試結果。 但是’最好能夠防止來自鏡子邊緣的分散光線7到達光線 所指定的目標電池附近之電池上。 為達此目的’習知技術將朝向電池行進的光線封閉於管子 或通道内it些f子或通道的側壁阻止任何光線朝向並非指 疋的電池刖看出這些管子或通道的重複使得此裝置 097147605 200933777 變得很笨重,且增加了過多的重量。 為了避免此種沉重的方式,可將一個或多個螢幕8插入鏡 子2與欲測試的光電電池4之間,這些螢幕8是很簡單的穿 孔板。指向電池的光線10可通過開口 11,同時,不想要的 分散光線7被螢幕的不透明壁所阻擋。 本發明的裝置特別適用於測試含有多個透鏡的光電面 板,這些透鏡係用以將來自鏡子的光線集中於電池上。 φ 【圖式簡單說明】 圖1是從上方顯示本發明第一實施例的裝置之局部示意 圖,其中顯示出鏡子與電池的配置情形。 圖2是類似於圖1用以顯示本發明第二實施例的圖式,其 中添加了橫向螢幕,此實施例是較佳的實施例。 【主要元件符號說明】 1 光源 2 鏡子 3 支架 4 光電電池 5 雙箭頭 6 轴 7 光線 8 螢幕 9 光線 097147605 200933777 ίο 光線 11 開口 097147605
