    描述

    光焱科技的 TPCV 系統有 4 個主要特色:

    1. 高速時間分辨率 High Time-Resolution
    2. 卓越信躁比 High Signal/ Noise Ratio
    3. 多功能且直觀的軟體 Versatile and intuitive software
    4. 超高性價比 High Cost-Performance Ration

    特點

    1. 高速時間分辨率

    TPC/TPV測試需要能夠因應極快速時間分辨的高速儀器,這在涉及到微秒甚至納秒等級超短時間範圍,對許多檢測設備而言是一個重大挑戰。
    光焱科技(Enlitech)的TPCV測試儀使用的激發激光器工作在520nm波長,具有以納秒計的快速上升和下降時間。
    這種快速操作對於研究所有類型的鈣鈦礦PVK和有機太陽能電池OPV中的瞬態光電流是精準量測的重要關鍵。

    2. 卓越信躁比

    TPC/TPV 訊號很精密,很容易被測量系統內的雜訊所掩蓋。未能 獲得準確的 TPC/TPV 數值,檢測設備需要最大限度地減少各種雜訊以提高精度與準確度。

    Enlitech 的 TPCV 測試儀整合了二十年在光學與電學等訊號處理和降噪方面的專業知識。 從系統的設計,包括佈線、訊號處理電路、電磁屏蔽等方面,都表現出優異的雜訊抑制能力。 這使得測試數據具有高信噪比,從而獲得更精確的結果,並使研究人員有信心進一步改進他們的研究結果。

    3. 多功能且直觀的軟體-簡化的流程和有效的資料創建

    一般來說,TPC/TPV測試系統整合了各種先進的硬體設備,例如超快雷射和電子訊號擷取設備,例如訊號擷取卡或示波器等。使用這些設備可以讓我們擷取準確的電子訊號並進行分析。將這些訊號資料準確地傳輸到電腦系統。 隨後,這些捕獲的訊號資料將被發送到專用的分析程序進行處理。 在程式中,我們使用特定的公式對訊號資料進行擬合和分析,以便解析和理解這些資料。 這個過程有助於我們深入了解鈣鈦礦或有機太陽能電池裝置的性能。

    在 TPC/TPV 測試過程中,一套全面且整合的軟體可以顯著提升使用者效率並快速產生高品質數據。光焱科技的 TPCV 測試儀軟體擁有此類多工處理能力和使用者友善的介面。它不僅可以控制各種硬體設備,還可以快速將訊號擷取到電腦中。此外,該軟體還包含一個用於載子壽命分析的三級擬合功能,讓使用者能夠直接完成測試和數據分析,獲取有關鈣鈦礦或有機太陽能電池載子壽命的資訊,為使用者帶來便利。

    4. 超高性價比

    組裝 TPC/TPV 測試系統需要精密協調先進的儀器,這項任務既昂貴又複雜,需要進行大量的光路開發和訊號整合,以及數據分析軟體的開發。

    光焱科技的 TPCV 測試儀提供了一套交鑰匙解決方案,採用最先進的元件,由擁有二十年整合經驗的工程師組裝而成。只需一天的培訓,該系統即可投入使用,提供即時的數據生成能力。

    光焱科技的 TPCV 系統成本與單獨購買元件的成本相當,其時間效率非常出色,使研究人員能夠以極高的成本效益專注於鈣鈦礦太陽能電池的發展。

    圖為光焱科技 TPCV 系統圖。

    系統圖概述了光焱科技用於 TPC/TPV 測量的 TPCV 系統。它顯示了一個快速雷射和驅動器,產生一個以奈秒為時間尺度的雷射光束,並將其指向待測元件 (DUT)。然後,待測元件產生一個由訊號擷取設備捕捉的暫態訊號。最後,來自該設備的數據被發送到電腦系統進行數據分析。此流程圖展示了從初始雷射激發到最終分析太陽能電池響應的過程。

    應用

    二氧化錫SnO2 與二氧化鈦TiO2 在鈣鈦礦太陽能電池中的比較:增強的電荷動力學——使用 TPC/TPV 進行的《Nature Energy》研究

    TPCV-Application-Perovskite-Solar-Cel-1

    圖為 TPCV 在研究二氧化錫與二氧化鈦在鈣鈦礦太陽能電池中的應用。

    這篇發表在《Nature Energy》期刊上的文章詳細研究了使用二氧化錫作為電子傳輸層來提高鈣鈦礦太陽能電池中電子提取效率的方法。透過仔細的 TPC/TPV 分析,研究人員證明,二氧化錫不僅比二氧化鈦更有利於電荷提取,而且有助於減少遲滯現象,從而使太陽能電池更穩定、更高效。該論文強調了選擇合適材料以優化電荷傳輸機制的重要性,並突出了二氧化錫在能源應用中顯著提高鈣鈦礦太陽能電池效能的潛力。

    有機太陽能電池載流子動力學 TPC/TPV壽命分析結果

    TPCV-Application-OPV.01

    上圖顯示一個比較不同有機太陽能電池樣本載流子壽命的TPC(瞬態光電流)圖表。每條曲線代表一個不同的樣本,從A-4標記到E-4,並顯示了相關的載流子壽命τ_c(以微秒為單位)。標準樣本以虛線標記,指示出10.8微秒的載流子壽命,作為與被測試樣本對照的基準。

    TPCV-Application-OPV.02

    圖為有機太陽能電池的 TPV 曲線。此圖顯示了一個 TPV(暫態光電壓)圖表,顯示了幾個有機太陽能電池樣品的電壓隨時間的衰減情況。與 TPC 圖表一樣,樣品從 A-4 到 E-4 進行識別,並以毫秒為單位標記其電壓壽命 τ_v。標準樣品再次作為參考,其電壓壽命為 0.503 毫秒,其他樣品的效能可以與之比較。

    在太陽光電研究中,了解太陽能電池材料內部電荷載子(電子和電洞)的複雜運動至關重要。這種運動決定了太陽能電池將陽光轉換為電能的效率。這兩張描繪 TPC 和 TPV 測量的圖像,讓我們得以一窺這個微觀世界。

    TPC 圖表顯示了各種有機太陽能電池樣品在被光激發後,產生的電子和電洞複合的速度。較短的載子壽命 τ_c 意味著更快的複合速度,這不利於太陽能電池的效率。標準樣品建立了一個基準,其 τ_c 為 10.8 微秒,這是一個相對較慢的速度,表明電荷分離效果更好,因此可能具有更高的效率。

    另一方面,TPV 圖表顯示了由這些電荷分離產生的電壓隨時間衰減的速度。較長的電壓壽命 τ_v 通常表示材料可以更長時間地維持電荷載子的分離,從而更有效地從太陽能電池中提取能量。

    綜合來看,這些測量結果提供了對太陽能電池效能和「健康狀況」的洞察。透過比較各種材料,例如這裡顯示的樣品,研究人員可以確定哪些成分和結構為電荷載子提供了最佳路徑,從而提高太陽能轉換效率。這種電荷運動以圖表和數字表示,是太陽能電池技術中載子動力學理論的核心。

    TPC和TPV是太陽能電池性能測試中的兩個重要參數,分別代表瞬態光電流(Transient PhotoCurrent)瞬態光電壓(Transient PhotoVoltage)。它們對太陽能電池的元件轉換效率有著直接的影響。

    TPC是指在太陽能電池接收到光照時產生的電流的瞬態變化。這個參數反映了電池中光生電荷載流子的收集效率。TPC測量則關注電荷載體的生成、傳輸和收集效率,直接影響電池的功率輸出和效率。這些測試對於設計更高效、更可靠的光伏系統相當重要,使研究人員能夠精確調控電池內部過程,開發出性能更優更高效率的太陽能電池。如果TPC較低,意味著電池內部的電荷載流子收集速率慢,這可能會導致由於複合和擴散而產生的顯著損失。通過測量TPC,可以確定電池的內部電阻,進而找出提高光生電荷收集效率的改進方向。

    TPV是指在太陽能電池接收到光照時產生的電壓的瞬態變化。這個參數反映了電池中光生電荷載流子的分離效率。如果TPV較低,可能表明p-n結的質量較差、摻雜水平低,或者帶隙與太陽能電池的光譜響應不匹配。通過測量TPV,可以瞭解p-n結的質量,並找出提高光生電荷分離效率的改進方向。通過TPV測量,可以分析電荷載體的生命週期和重組機制,幫助減少能量損失,提高電池的能量轉換效率和穩定性。

    以鈣鈦礦太陽能電池為例,TPC和TPV的測量可以幫助我們優化電池結構和材料,提高光生電荷的收集和分離效率,進而提高太陽能電池的轉換效率。比如,通過改善鈣鈦礦層的質量,減少缺陷,可以提高TPC和TPV,從而提高電池的整體效率。

    TPC與TPV測量太陽能電池隨時間變化的瞬態光電流和光電壓,以分析光生電荷載流子的傳輸機制,並獲得電荷轉移壽命(來自 TPC)和電荷複合壽命(來自 TPV)。 系統利用快速激光源照射光伏原件,產生光電流或光電壓信號,並進行時域測量和分析,獲得瞬態光電壓(TPV)和瞬態光電流隨時間的變化曲線,用於了解光伏器件的內部結構和載流子動力學。

    1. 動態性能評估:TPCV可以説明評估太陽能電池在光照條件變化或負載變化時的動態回應速度和穩定性。
    2. 設計優化: 通過瞬態光電流和瞬態光電壓的測量,可以瞭解到太陽能電池在不同光照條件下的性能特性。
    3. 系統穩定性:太陽能電池系統的穩定性取決於其對光照變化的回應速度和穩定性。通過評估瞬態光電流和瞬態光電壓,可以確定太陽能電池系統在光照變化時的動態行為,從而確保系統的穩定性和可靠性。
    4. 性能預測:TPCV提供了對太陽能電池在不同光照條件下的性能預測能力。這有助於太陽能電池製造商和系統設計者預測太陽能電池在不同環境條件下的性能,從而更好地滿足實際應用需求。
