太陽能電池效率量測系統

Solar Cell Efficiency Measurement and Analysis System



 

 

簡介:
   太陽能電池是可再生能源中具有發展性的一種,只要在太陽光充足的區域,就可以將光能轉換為電能,故在石化能源短缺及溫室效應的考量下,具有相當大的未來性。光電元件的種類眾多,主要的應用為發光二極體、太陽能電池及光偵測器等等,其元件特性與其電流電壓曲線有很大的相關性,從單一PN接面到多接面的元;從本質接面到異質接面;從表面微結構到主動層的奈米結構設計,各有不同的電流電壓曲線特徵。藉由電流電壓曲線的量測與分析,將有助於了解光電元件材料的特性,促進實驗室技術開發或產線上的良率與製程調整。在模擬太陽光光源下進行量測電流電壓曲線,可量測出太陽能之能量轉換效率及相關之特性如:開路電壓(Voc)、短路電流(Jsc)、理想因子(FF)、串聯電阻(Rs)與並聯電阻(Rsh)。

  


 Real-time analysis results (parameters such as Jsc, Voc, FF, Rs, Rsh, and Efficiency) for light IV curve

 Fast and easy measurement

 Accurate measurements

 Excellent repeatability

 Extraction of diode parameters from dark IV curve (ideality factor and saturation current)

 Temperature coefficient measurement of solar cells (optional)

 Temperature stability and reliability test platform (optional)

 Light induced degradation (LID) investigation (optional)


  The IV curve measurement of solar cell under illumination is most important for performance analysis. The quick extraction of parameters such as short circuit current (Jsc), open circuit voltage (Voc), fill factor (FF), sheet resistance (Rs), and shunt resistance (Rsh) is a basic requirement. The model fitting can provide further information of saturation current (Jo) and ideality factor (n) for junction quality evaluation.
