波音公司的高技术中心在太阳电池效率方面取得了重要进展,其双结空间聚光电池光电转换效率已超过31％。这种电池由砷化镓顶层和吸收红外光的锑化镓底层制成。在技术上,效率递增的速度一般只有1～2％,但是波音公司却在Varian联合公司的24.1％空间电池效率基础上提高了7％。这一电池效率已由NASA路易斯研究中心在模拟空间条件(AM0)下进行了验证。波音公司的新型太阳电池在地面应用时也能正常工作,效率达37％。据波音公司太阳电池规划部经理刘易斯·弗雷斯讲,取得这一成绩的关键是如何选择机械压接式叠层太阳电池第二层所用的半导体材料。波音公司太阳电池的顶层为标准砷化镓(GaAs)太阳电池。通过各种方法检测后,波音公司的研究
Boeing’s high-tech center has made significant progress in solar cell efficiency, and its double junction space concentrator cells have achieved over 31% photoelectric conversion efficiency. This battery is made of a gallium arsenide top layer and a bottom layer of gallium antimonide that absorbs infrared light. Technically, the rate of efficiency is generally only 1-2% faster, but Boeing 7% increase in Varian United’s 24.1% space battery efficiency. This cell efficiency has been validated by NASA’s Lewis Research Center under simulated space conditions (AM0). Boeing’s new solar cell also works well when used on the ground, with 37% efficiency. According to Lewis Fresse, solar cell planning manager at Boeing, the key to achieving this result is how to choose the semiconductor materials used in the second layer of a mechanical crimp-type laminated solar cell. The top of the Boeing solar cell is a standard GaAs solar cell. After various methods of testing, Boeing Research
