聚光型高效率太陽能電池

摘要：本文闡述了聚光型太陽能發電系統高效率化和低成本化的可能性，以及由聚光型多結太陽能電池/ 模塊技術開發所取得的成果。基于Ⅲ - Ⅴ族化合半導體技術的InGaP/InGaAs/Ge 3 結聚光電池，最高的光電轉換效率已達到40.7%，如利用4 結、5 結等多結化聚光電池，還可望實現50% 的超高效率化。 敘詞：太陽能，聚光太陽能電池，模塊 Ⅲ - Ⅴ族化合物，高效率，低成本 Abstract：The concentrating solar cell photovoltaic generation system capable of high efficiency and low cost, and the efforts result frommulti-junction concentrating solar cell/module development are introduced in this paper. The three-junction concentrating solar cell InGaP/InGaAs/Ge based on　-V family chemical compound semiconductor technology, its maximum efficiency of photo-electro conversionbecame 40.7%. If four-junction/five-junction etc multi-junction. Concentrating solar cell is adapted, 50% super high efficiency can berealized.
