本論文主要在探討太陽能電池量測系統中包括量測的方法、量測軟硬體和量測接線法等,對於太陽能電池各項參數的影響,因為太陽能電池工廠的量測機台少則花費百萬元購買,並定時校正,量出的數據較為精確,以原廠的量測數據為目標,探討如何運用實驗室現有資源,克服量測環境問題,使量測結果能趨近太陽能電池原廠的量測結果,進而提升量測太陽能電池參數的精準度。
一開始先從理論中了解,串聯電阻和並聯電阻對太陽能電池的轉換效率、填充因子、開路電壓、短路電流等參數的影響,第二步驟建立太陽能電池等效電路模型,用Spice程式模擬串聯電阻和並聯電阻對太陽能電池各項參數的影響。第三步驟實際使用2-wire 2針量測方法和採用2-wire 4針量測法、2-wire 6針量測法,量測多晶矽太陽能電池,後兩種方法是將量測導線並聯,目的要降低量測導線的電阻,因為量測時的導線電阻,對於量測系統而言,會將其視為太陽能電池的串聯電阻,進而影響量測的精準度。第四步驟使用4-wire 4針量測法,其目的也是要有效的降低導線電阻。
期望能利用現有量測系統的軟硬體功能,做一些改善研究,在量測太陽能電池的各項參數時,可取得更精確數據。不會因為量測的方法、量測軟硬體和量測接線法等外在因素,影響量測太陽能電池參數的精準度。
This research focused on the improvement of solar cells conversion efficiency by modifying the measuring configurations. The measuring configurations are composed of both hardware and software including the methods of testing, the software of testing and the leads of testing ,etc. The goal is to assure the result of testing data and are incoordinate with the solar cell manufacturer’s data. Because the testing equipment of solar cell manufacturer were calibrated regularly, it should be much more accurate.
At first, we need to understand the series resistances and shunt resistances how to influence the performance parameters of solar cells, which include conversion efficiency , fill factor , open-circuit voltage and short-circuit current . Second ,I build up a solar cell equivalent circuit model by Spice program. By simulating, I understand the relations between all these solar cell performance parameters .The third , I use the testing methods of 2-wire 2 pins ,2-wire 4 pins,2-wire 6pins,4-wire 4 pins to measure the solar cells practically ,and modify the testing software to activate the 4-wire function in the source meter .
By reducing series resistances through changing those key factors ,improving the conversion efficiency and fill factor . A more accurate data was obtained which give us a more solid confidence for further solar cell experiment and measurement .
