Description
本發明是有關於一種太陽能電池。
太陽能似乎是一種用之不竭的能源,因此太陽能的相關研究引起許多注意。太陽能電池便是為了將太陽能直接轉換成電能而開發的裝置。
近年來,硒化銅銦鎵薄膜太陽能電池受到極大關注,因為硒化銅銦鎵(Copper indium gallium(di)selenide,CIGS)薄膜具有較佳的光電轉換效率。CIGS薄膜必須與一N型半導體材料搭配並形成一PN接面,才能成為太陽能電池。在目前的技術中,以硫化鎘(CdS)搭配CIGS的光電轉換效率最高。但是,硫化鎘卻是污染性極高的材料,許多國家不允許使用硫化鎘。因此,也造成CIGS薄膜太陽能電池的應用受到很大的限制。
有鑑於此,目前亟需一種改良的太陽電池,期能具有高的光電轉換效率,並能符合環境保護的要求。
本發明之一目的係提供一種太陽能電池,俾能具有高光電轉換效率以及高開路電壓。
本發明之另一目的係提供一種太陽能電池,其中不包含硫化鎘之高污染性物質。
本發明之再一目的係提供一種太陽能電池,俾能在高溫下維持較佳的光電轉換效率。
此太陽能電池包括一第一導電層、一光電轉換層以及一第二導電層。光電轉換層用以將光線轉換為電能。光電轉換層位於第一導電層上方。光電轉換層包含一硒化銅銦鎵層以及一矽基材。硒化銅銦鎵層接觸矽基材,使硒化銅銦鎵層與矽基材間形成一異質PN接面。第二導電層位於光電轉換層上方。第一及第二導電層用以傳輸電能。
為了使本揭示內容的敘述更加詳盡與完備,下文針對了本發明的實施態樣與具體實施例提出了說明性的描述;但這並非實施或運用本發明具體實施例的唯一形式。以下所揭露的各實施例,在有益的情形下可相互組合或取代,也可在一實施例中附加其他的實施例,而無須進一步的記載或說明。
在以下描述中,將詳細敘述許多特定細節以使讀者能夠充分理解以下的實施例。然而,可在無此等特定細節之情況下實踐本發明之實施例。在其他情況下,為簡化圖式,熟知的結構與裝置僅示意性地繪示於圖中。
第1A圖繪示本發明一實施方式之太陽能電池100的剖面示意圖。太陽能電池100包括第一導電層110、光電轉換層120以及第二導電層130。
光電轉換層120位於第一導電層110與第二導電層130之間,並且電性連接第一導電層110以及第二導電層130。光電轉換層120可將光線轉換為電能,所產生的電能經由第一導電層110以及第二導電層130傳輸至一外部負載裝置(未繪示)。
光電轉換層120包含硒化銅銦鎵層122以及矽基材124。硒化銅銦鎵層122接觸矽基材124,使硒化銅銦鎵層122與矽基材124間形成一異質PN接面123。
根據本發明之一實施例,光電轉換層120中不包含硫化鎘。在習知技術中,通常會形成一硫化鎘層於硒化銅銦鎵層122上,用以形成PN接面。但是,硫化鎘具有極高的污染性,很多國家不允許使用硫化鎘。因此,根據本發明之實施方式的太陽能電池,能夠廣泛地被應用。
本發明之另一特徵是硒化銅銦鎵層122接觸矽基材124而形成異質PN接面123。硒化銅銦鎵與矽所形成的異質PN接面,可使太陽能電池100具有較小的反向飽和電壓(reverse saturation current)以及更高的開路電壓(open-circuit voltage)。較小的反向飽和電壓可使太陽能電池的漏電損失降低。高的開路電壓可使太陽能電池具有較佳的光電轉換效率。
硒化銅銦鎵層122可為P型硒化銅銦鎵或N型硒化銅銦鎵。在硒化銅銦鎵層122為P型硒化銅銦鎵的實施方式中,矽基材124為N型矽基材124。矽基材124可包含一重摻雜區域126。重摻雜區域126位在矽基材124鄰近第一導電層110的表面附近。在此實施方式中,重摻雜區域126為N+重摻雜區域(N+ region),用以提高太陽能電池100的內建電場。因此,重摻雜區域126亦可稱為表面電場層。在另一實施方式中,硒化銅銦鎵層122為N型硒化銅銦鎵,且矽基材124為P型矽基材124。在此實施方式中,重摻雜區域126為P+重摻雜區域,重摻雜區域126位在矽基材124鄰近第一導電層110的表面附近。
上述矽基材124可例如為單晶矽晶圖或成長於其他基板上之單晶矽、多晶矽或非晶矽。矽基材124的厚度可例如為約100至約500 μm。
在一實施方式中,硒化銅銦鎵層122在厚度方向上具有一鎵濃度分佈。例如,在硒化銅銦鎵層122接觸矽基材124的一側,硒化銅銦鎵層122中的鎵濃度較小。反之,在遠離矽基材124之另一側,硒化銅銦鎵層122中的鎵濃度較高,如第1A圖所示。本案發明人發現,雖然硒化銅銦鎵層122中的鎵濃度越高,可使開路電壓提高。不過,在某些實施方式中,卻可能同時導致太陽能電池100的溫度係數降低。換言之,會造成太陽能電池在高溫下的光電轉換效率大幅下降,而導致太陽能電池整體效率降低。因此,在本實施方式中,硒化銅銦鎵層122具有一鎵濃度分佈,以降低溫度對於太陽能電池效率的影響程度。從而,使太陽能電池不但在常溫下具有較高光電轉換效率,並且在高溫下維持這樣的效率。硒化銅銦鎵層122的鎵元素成分比例可例如為鎵元素/(鎵元素+銦元素)比例約0.2至0.9。
硒化銅銦鎵層122與矽基材124兩者都具有光電轉換的特性。因此,當光線穿透硒化銅銦鎵層122時,未被硒化銅銦鎵層122吸收的光線,可再被矽基材124吸收並被轉換成電能。因此,根據本發明之實施方式,具有極高的光電轉換效率。
可使用共蒸鍍、濺鍍、印刷或其他製造方法在矽基材124上形成硒化銅銦鎵層122。在一實施例中,硒化銅銦鎵層122的厚度H為約0.1 μm至約5μm,明確地為約0.1 μm至約2 μm,更明確地為約0.1 μm至約1 μm。因此,相較於習知技術,根據本發明之實施方式,可具有較小的硒化銅銦鎵層厚度。
第一導電層110及第二導電層130分別配置於光電轉換層120的兩側,用以傳輸光電轉換層120所產生的電能。具體而言,光電轉換層120位於第一導電層110上方,第二導電層130位於光電轉換層120上方。第一導電層110及第二導電層130可藉由各種物理氣象沈積技術來形成。
在第1A圖繪示的實施方式中,光線由第二導電層130的一側進入太陽能電池100。因此,第二導電層130為一透明導電層,其可例如為氧化銦錫、氧化鋅、氧化錫或氧化鋅鎂等材料所製成。第二導電層130的厚度可例如為約50至約100 nm。第一導電層110為一金屬層,其可例如為鋁或銀等金屬所製成。
硒化銅銦鎵層122可配置在矽基材124的上方或下方。在一實施例中,銦鎵層122位於第二導電層130與矽基材124之間,如第1A圖所示。在另一實施例中,如第1B圖所示,硒化銅銦鎵層122可位於第一導電層110與矽基材124之間。
在一實施方式中,太陽能電池100可更包括有一反射層140,如第1A圖所示。反射層140位於光電轉換層120的下方,用以反射未被吸收的光線,例如波長較長的光線。在一實例中,反射層140並非金屬材料所製成。例如,反射層140可為氧化銦錫、氧化銦鎢、或氧化鋅摻雜鋁或鎵等導電氧化物所製成。反射層140也可利用非導電材料來製造,例如氧化矽。在反射層140為非導電材料的實施方式中,反射層140可具有複數個接觸窗142,使第一導電層110能夠經由接觸窗142電性連接至光電轉換層120。
在又一實施方式中,太陽能電池100可更包括有一輔助電極150,如第1A圖所示。輔助電極150位於第二導電層130上,且為圖案化之電極。例如,輔助電極150可具有一矩陣形狀圖案(格線狀圖案)。輔助電極150可例如為鋁或銀等高導電率之金屬材料所製成。
在一實施方式中,太陽能電池100之矽基材124其與第一導電層110接觸之一側,更可利用佈植或是擴散的方式,使其具有更高濃度的重摻雜區域而形成背後電場(圖未示),其中該背後電場位於矽基材124與第一導電層110之間。
第2圖繪示本發明一實施方式之太陽能電池100與習知技術之CIGS太陽能電池的電流密度與電壓的關係曲線圖。在第2圖中,曲線A表示習知技術之CIGS太陽能電池,曲線B表示本發明一實施方式之太陽能電池100。根據本發明實施方式之太陽能電池100的開路電壓以及電流密度明顯高於習知技術之CIGS太陽能電池。
第3圖繪示本發明三個不同實施例之太陽能電池100的電流密度與電壓的關係曲線圖。曲線C表示矽基材124中沒有重摻雜區域126的實施例。曲線D表示矽基材124中有重摻雜區域126的實施例。曲線E表示矽基材124中有重摻雜區域126,且硒化銅銦鎵層122具有一鎵濃度分佈的實施例。由第3圖可知,硒化銅銦鎵層具有鎵濃度分佈的實施例(曲線E)的開路電壓以及電流密度高於其他兩個實施例。
雖然本發明已以實施方式揭露如上,然其並非用以限定本發明,任何熟習此技藝者,在不脫離本發明之精神和範圍內,當可作各種之更動與潤飾,因此本發明之保護範圍當視後附之申請專利範圍所界定者為準。
