M434186 五、新型說明: [0001] 【新型所屬之技術領域】 本創作是有關於一種聚光型太陽能接收器,特別是有關 於一種整合電容器於接收器之基板上,在太陽能電池停 止供電時提供電能,以維持發電穩定度的聚光型太陽能 接收器。 [0002] • 【先前技術】 目前,地球能源正值日益耗竭,因此開發替代能源及再 生資源刻不容緩。太陽能發電是對環境影響較小,並且 具備永續發展的再生能源之一,其中,聚光型太陽能系 統與其他綠色能源的發電方法相比,具有相對高的發電 量以及發電成本低的優點,特別適用於大型發電廠的建 置。 [0003] • 大部分的聚光型太陽能系統只能吸收直射日照光,因此 必須搭配雙軸追日系統,如太陽光感測器、控制器、驅 動馬達及精密齒輪等,使太陽能模組保持向陽的狀態, 以聚焦太陽光於太陽能電池上。由於聚光型太陽能系統 只接受直射曰照太陽光,因此發電量很容易受到振動, 造成追曰系統角度偏移而急速下降。如第1圖所示,其顯 示聚光型太陽能電池一曰中的發電量變化,由圖中可以 發現當直射日照量因風吹振動、浮雲遮蔽或其他因素造 成下降時,聚光型太陽能系統的整體發電量也會隨之波 動。 [0004] 另一方面,聚光型太陽能系統也容易因為太陽光感測器 (sun 1 i ght sensor)追日演算法的回授控制而助長波動 101204G3# 單編號 A_ 第3頁/共16頁 1012012954-0 M434186 ,一旦追曰系統的誤差超過可容許角(acceptance angle),聚光的焦點將偏移太陽能電池的範圍,使整個 聚光型太陽能系統的發電量瞬間降為零。如第2圖所示, 聚光型太陽能系統之可容許角為1. 3°,若追蹤誤差超過 可容許角,將使發電量急速下降,不但會造成聚光型太 陽能系統後端直流-交流變流器(DC/AC inverter)的輸 入及輸出電力不穩定,同時也會因為變流器不斷重新啟 動相位及最大功率追縱(Maximum Power Point Tracking,MPTT)以並聯到市電,而重新啟動的時間, 系統雖可發電,但無法提供輸出至負載,如此將會降低 整體的發電量及變流器的效能。 [0005] 目前在改善聚光型太陽能系統因外在環境的瞬間改變而 造成發電量不穩的問題方面,以加強模組及追日系統結 構的方式居多。解決發電量不穩定的方法有:(1)增加 硬體的精度,以減少追曰系統誤差。(2)改善光學設計, 搭配二次光學以增加可容許角。(3)加強追曰支架的結構 強度及重量,或加上額外的緩衝材料以減少振動。然而 ,這些方法改善對於發電量的改善有限,從成本及耗電 量的角度來看,增加硬體精度會增加極大的製造成本。 另外,從機構來減震也具有造成更大鋼鐵成本以及更多 追曰耗電量的缺點,且隨著聚光型太陽能系統大型化的 趨勢,其所需的硬體成本將會更大。 [0006] 另外,由於聚光型太陽能系統發電量不穩的發生通常是 短暫的瞬間,一旦追日系統再度對準太陽,太陽能模組 的輸出與發電量不穩前的差異不大,若能輔以穩壓的電 10120403^^^^ A〇101 第4頁/共16頁 1012012954-0 M434186 路元件來維持此段不穩時間的發電,將可降低因追曰系 統振動造成發電量不穩的效應。因此,有必要提出一種 提升聚光型太陽能系統發電穩定度及低成本的改善方法 〇 【新型内容】 [0007] 有鑑於上述習知技術之問題,本創作之目的就是在提供 一種聚光型太陽能接收器,以解決習知聚光型太陽能系 統受振動而造成瞬間輸出電量不穩定,且改善發電量不 穩定及成本過高的問題。 [0008] 根據本創作之目的,提出一種聚光型太陽能接收器,其 包含基板、太陽能電池、二極體電路以及電容器。太陽 能電池可焊接於基板之上方;二極體電路可焊接於基板 之上方;以及電容器,包含電極層及介電層,可設置於 .基板之上方,電極層為銅,且介電層為一薄膜化複層結 構。其中,電容器可於太陽能電池停止供電時提供電能 ,以維持太陽能發電系統之穩定度。 [0009] 其中,基板之材質可為覆銅陶究(Di rect Bond Copper ,DBC),覆銅陶瓷可包含陶瓷材料及銅箔,銅箔可燒結 於陶瓷材料之上方,以形成覆銅陶瓷。 [0010] 其中,陶瓷材料可包含氧化鋁或氮化鋁。 [0011] 其中,太陽能電池可為矽晶圓太陽能電池、奈米晶太陽 能電池、銅銦硒系太陽能電池、銅銦鎵硒系太陽能電池 、三五族太陽能電池及染料敏化太陽能電池其中之一或 其組合。 101204G#單編號 A〇101 第5頁/共16頁 1012012954-0 M434186 [0012] 其中,太陽能電池、二極體電路及電容器可與基板電性 相連。 [0013] 其中,太陽能電池以導線與基板電性連接。 [0014] 其中,導線之材質可包含金屬、金屬化合物及奈米碳材 其中之一或其組合。 [0015] 其中,電容器可為陶瓷電容器、鋁質電解電容器、钽質 電容器、雲母電容器、紙質電容器、金屬化塑膜電容器 、塑膠薄膜電容器及超級電容其中之一或其組合。 4 [0016] 其中,薄膜化複層結構可包含非晶質類鑽碳膜。 [0017] 承上所述,因依本創作之聚光型太陽能接收器,其可具 有一或多個下述優點: [0018] (1)此聚光型太陽能接收器之電容器,係採用物理氣相 沉積(Physical Vapor Deposition,PVD)之滅鑛技術 (sputtering deposit ion)整合至聚光型太陽能接收器 之基板上,以降低成本。 [0019] (2)此聚光型太陽能接收器中之電容器,係以非晶質類 - 鑽碳膜為介電層,其具備高緻密性及高附著性,可提供 有效之介電性與介電層奈米化之效果,以達到降低體積 與提升儲電密度之目的。 [0020] (3)此聚光型太陽能接收器可藉由電容器之設置,提供 蓄電池與負載所需之電能,以維持聚光型太陽能系統發 電之穩定度。 [0021] 茲為使貴審查委員對本創作之技術特徵及所達到之功效 10120403^單编號刪丨 第6頁/共16頁 1012012954-0 M4.34186 有更進一步之瞭解與認識,謹佐以較佳之實施例及配合 詳細之說明如後。 【實施方式】 [0022] 為利貴審查員瞭解本創作之技術特徵、内容與優點及其 所能達成之功效,茲將本創作配合附圖,並以實施例之 表達形式詳細說明如下,而其中所使用之圖式,其主旨 僅為示意及輔助說明書之用,未必為本創作實施後之真 實比例與精準配置,故不應就所附之圖式的比例與配置 關係解讀、侷限本創作於實際實施上的權利範圍,合先 敘明。 [0023] 以下將參照相關圖式,說明依本創作聚光型太陽能接收 器之實施例,為使便於理解,下述實施例中之相同元件 係以相同之符號標示來說明。 [0024] 請參閱第3圖,其係為本創作之聚光型太陽能接收器之第 一實施例之示意圖。圖中,聚光型太陽能接收器3包含基 板30、陶瓷材料301、銅箔302、太陽能電池31、導線 311、二極體電路32以及電容器33。基板30之材質可為 覆銅陶兗(Direct Bond Copper,DBC),此覆銅陶完可 包含陶瓷材料301及銅箔302,且銅箔302可直接燒結於 陶瓷材料301之上方,以形成覆銅陶瓷,其陶瓷材料301 可進一步包含氧化鋁或氮化鋁,但不以此為限。太陽能 電池31可焊接於基板30之上方,並以複數個導線311與基 板30電性連接;其太陽能電池31之材料可包含矽晶圓太 陽能電池、奈米晶太陽能電池、銅钢础系太陽能電池、 銅銦鎵硒系太陽能電池、三五族太陽能電池及染料敏化 1()12{)4()3_單編號A0101 第7頁/共16頁 1012012954-0 M434186 太陽能電池其中之一或其組合,但不以此為限。而導線 311之材質可包含金屬、金屬化合物及奈米碳材其中之一 或其組合等,具有導電性之材料,以使基板30與太陽能 電池31可電性相連。二極體電路32可直接焊接於基板3 0 之上方,以電性連接太陽能電池31、電容器33以及負載 。電容器33可設置於基板30之上方,其包含陶瓷電容器 、鋁質電解電容器、鈕質電容器 '雲母電容器、紙質電 容器、金屬化塑膜電容器、塑膠薄膜電容器及超級電容 等其中之一或其組合,但不以此為限。其中,電容器33 可於太陽能電池31停止供電時提供電能,以維持太陽能 發電系統之穩定度。 [0025] 更進一步地說,本創作之聚光型太陽能接收器3中之電容 器33,可採用物理氣相沉積(Physical Vapor Deposition,PVD)之滅鐘技術(sputtering deposition)整合至聚光型太陽能接收器3之基板30上。 電容器33之電極層材質可為銅;而介電層則需具備高sp3 含量、高緻密度、高附著性之薄膜化複層結構,以提供 有效的介電性及介電層奈米化效果,並達到降低體積與 提升儲電密度之目的。 [0026] 請參閱第4圖,其係為本創作之聚光型太陽能接收器之第 二實施例之第一示意圖。圖中,包含太陽光4 0、太陽能 電池41、蓄電池421、電容器422、變流器423以及負載 43。太陽能電池41可焊接於聚光型太陽能接收器之基板 之上,其可為石夕晶圓太陽能電池、奈米晶太陽能電池、 銅銦硒系太陽能電池、銅銦鎵硒系太陽能電池、三五族 10120403^^^^ A〇101 第8頁/共16頁 1012012954-0 M434186 太陽能電池及染料敏化太陽能電池其中之—或其組合, 但不以此為限,在本實施例中’其太陽能電池41較佳地 可為三五族太陽能電池。電容器422可藉由物理氣相沉積 (Physical Vapor Deposition,PVD)之濺鐘技術 (sputtering deposit ion)整合至聚光型太陽能接收器 之基板上,其電容器422可為陶瓷電容器、鋁質電解電容 器、叙質電容器、雲母電容器、紙質電容器、金屬化塑 膜電容器、塑膠薄膜電容器及超級電容其中之一或其組 合’但不以此為限。在本實施例中,電容器422較佳地可 為一超級電容。其中,電容器422之電極層材質可為銅, 且電容器422之介電層為薄膜化複層結構,以降低電容器 422之體積’並提升儲電密度;在本實施例中,其薄膜化 複層結構材質較佳地,可為非晶質類鑽碳膜。 [0027] 本實施例於實施上,是利用聚光型太陽能接收器中之太 1¾月t*電池41吸收直射的太陽光4〇,藉由太陽能電池41將 光能轉化為電能,並將電能提供給蓄電池421、電容器 422、變流器423及負載43。當聚光型太陽能系統之追曰 系統夂風吹震動而偏移或直射日照強度低,此時的太陽 能電地41雖可繼續生電,但無法將所生的電能輪出給蓄 電池421及負載43 ’將會導致發電量瞬間降低,而電容器 422即可輸出所儲存的電能給蓄電池421、變流器423及 負載43,以維持電壓的穩定。 [0028] 特別的是,本實施例中所使用的電容器422為超級電容5〇 ’請參閱第5圖’其係為本創作之第二實施例之第二示意 圖。如圖所示,超級電容50可進一步包含等效串聯電阻 10120403^^ A0101 第9頁/共16頁 1012012954-0 M434186 (Equivalent Series Resistance,ESR)501 及等效 並聯電組(Equivalent Parallel Resistance, EPR)502。等效串聯電阻501可在電流流經時造成電能的 損耗,並在充放電的瞬間影響超級電容50的輸出電壓瞬 間變化,使超級電容50能以較高、較快的速度充電及放 電。而等效並聯電阻5 0 2為超級電容5 0的漏電流路控5其 大小會影響超級電容50長時間的儲存效率。M434186 V. New description: [0001] [New technical field] The present invention relates to a concentrating solar receiver, in particular to an integrated capacitor on a substrate of a receiver, which is provided when the solar battery is powered off A concentrated concentrating solar receiver that maintains power generation stability. [0002] • [Prior Art] At present, the earth's energy is becoming increasingly depleted, so it is imperative to develop alternative energy sources and renewable resources. Solar power generation is one of the renewable energy sources that have little impact on the environment and have sustainable development. Among them, the concentrating solar energy system has the advantages of relatively high power generation and low power generation cost compared with other green energy power generation methods. Especially suitable for the construction of large power plants. [0003] • Most concentrating solar systems can only absorb direct sunlight, so it must be equipped with a dual-axis tracking system, such as solar sensors, controllers, drive motors and precision gears to keep solar modules The state of the sun to focus the sun on the solar cell. Since the concentrating solar system only accepts direct sunlight, the power generation is easily subject to vibration, causing the tracking system to shift angularly and rapidly. As shown in Fig. 1, it shows the change in power generation in a concentrating solar cell. It can be seen from the figure that when the amount of direct sunlight is reduced due to wind blow, cloud cover or other factors, the concentrating solar system The overall power generation will also fluctuate. [0004] On the other hand, the concentrating solar system is also prone to fluctuations due to the feedback control of the solar sensor (sun 1 i ght sensor). 101204G3# Single No. A_ Page 3 of 16 1012012954-0 M434186, once the error of the tracking system exceeds the acceptability angle, the focus of the concentrated light will shift the range of the solar cell, so that the power generation of the entire concentrating solar system is instantaneously reduced to zero. As shown in Fig. 2, the allowable angle of the concentrating solar system is 1. 3°. If the tracking error exceeds the allowable angle, the power generation will drop rapidly, which will not only cause the back-end DC-AC of the concentrating solar system. The input and output power of the converter (DC/AC inverter) is unstable, and the converter is restarted because the converter continuously restarts the phase and maximum power point tracking (MPTT) to connect to the mains. Time, although the system can generate electricity, but can not provide output to the load, this will reduce the overall power generation and converter performance. [0005] At present, in order to improve the problem that the concentrating solar energy system is unstable due to the instantaneous change of the external environment, the structure of strengthening the module and the system of chasing the Japanese system is mostly. The methods to solve the unstable power generation are: (1) increase the accuracy of the hardware to reduce the tracking system error. (2) Improve the optical design, with secondary optics to increase the allowable angle. (3) Strengthen the structure and strength of the tracking bracket, or add additional cushioning material to reduce vibration. However, these methods improve the improvement of power generation. From the perspective of cost and power consumption, increasing hardware accuracy increases the manufacturing cost. In addition, the shock absorption from the mechanism also has the disadvantage of causing greater steel cost and more power consumption, and as the concentrating solar system becomes larger, the hardware cost required will be greater. [0006] In addition, due to the unstable power generation of the concentrating solar energy system, it is usually a short-lived moment. Once the solar tracking system is again aligned with the sun, the difference between the output of the solar module and the power generation is not stable. Supported by the voltage regulator 10120403^^^^ A〇101 Page 4 / a total of 16 pages 1012012954-0 M434186 Road components to maintain this period of unstable power generation, will reduce the instability of power generation due to tracking system vibration Effect. Therefore, it is necessary to propose an improvement method for improving the power generation stability and low cost of the concentrating solar power system.
