In the paper we mainly researched space gainp2 / gaas / ge high efficiency tandem cells " making process by home - made low pressure mocvd technology and new solar concentrators. firstly, we presented reseached and development of solar cells in china and foreign countries ; secondly, on the basis of fundamental priciples and theories, we discussed some factors of influcing conversion efficiency of solar cells, and analysed the i - v output feature of two - junction tandem cells ; then the design concept of gainp2 / gaas / ge two - junction tandem cells was discussed, the detailed aspects of gainp2 / gaas / ge tandem cells epitaxy growth by low pressure mocvd was studied, and some questions on epitaxy growth ( such as crystal qualities, interface stress, element interdiffusion, n - and p - type doping et all ) were solved ; after that, the cell fabrication process was described ; finally, we reseached the hot pressing and mould process technology of an arched line - focus fresnel lens made by pmma, designed and fixed new solar concentrators
本文致力於用自製的低壓mocvd裝置進行cainp _ 2 / gaas / ge空間用高效級聯太陽能電池製作的工藝以及聚光太陽能電池組件的研究。首先，介紹了國內外太陽能電池的研究現狀及應用情況；其次，運用太陽能電池基本原理討論影響電池轉換效率的因素，分析了級聯電池的伏安特性；隨后，討論了cainp _ 2 / gaas / ge雙結級聯電池的結構設計理念，研究了採用低壓mocvd技術生長cainp _ 2 / gaas / ge級聯太陽電池材料的工藝過程，解決了異質材料生長的結晶質量、界面應力、材料互擴散以及材料n 、 p型摻雜等一系列問題；然後總結了級聯電池的后工藝製作；最後，研究了以pmma為材料的菲涅耳線聚焦透鏡的熱壓成型工藝及其模具的加工工藝，設計並安裝完成新型聚光太陽能電池組件。
