摘要: | 本論文以有機金屬氣相化學沈積法成長具有不同穿隧二極體摻雜濃度的多接面太陽能電池,並以同一晶片製作多接面太陽能電池樣品及穿隧二極體元件樣品。我們以RPV測試技術測定多接面太陽電池中穿隧二極體的Jpeak與Jvalley,並與單獨穿隧二極體元件的I-V特性做比較。實驗結果顯示,RPV測定的Jpeak誤差不超過6%,Jvalley的誤差較大可達50%。RPV所測得Jpeak的高準確性顯示此種測定技術應用多接面太陽能生產檢測的潛力。
本論文對RPV技術進行了原理探討、等效電路分析、以及實際的測試應用。這種技術的了解與發展,將有助於太陽能電池的製造與設計最佳化,應用於高聚光型太陽光伏系統時,可避免因穿隧二極體的品質不良所造成的損失。 This thesis reports on RPV method, which is able to characterize the tunnel junctions embedded in triple-junction solar cells. We used MOCVD to deposit solar cell structure with different tunnel junction designs. Solar cells and tunnel junctions were fabricated on the same wafer. RPV method was used to probe the peak and valley currents of the tunnel junctions embedded in the solar cells. The results were compared with the I-V characteristics measured from the tunnel junction. We found that the difference of Jpeak is within 6%. While Jvalley has larger deviation, may up to 50%. The small difference in Jpeak suggests the high validity of RPV method, which reveals its potential in testing triple-junction solar cells. In this thesis, we presented the operational principles, equivalent circuit analysis, and practical applications of RPV method. The understanding of this method will facilitate the design and fabrication of triple-junction solar cells. RPV method can be used to eliminate the loss due to the failure of tunnel junctions in solar cells. |
