【摘要】 为了给在高辐射轨道运行的卫星等航天器提供长寿命、强抗辐射太阳电池 ,设计了一种具有最佳结构的n+ i p+InP太阳电池。计算机模拟结果表明 ,即使经 10 17MeV·cm-2 和 10 18MeV·cm-2 的辐射辐照后 ,仍可具有 11%和 7%的转换效率 ;EOL(endoflife)功率质量比可达 10 0W /kg。无需防护罩 ,能够为运行在 32 0 0km极地轨道上的航天器稳定提供十年能量 ,这一指标超过了目前任何一种在研的太阳电池。特别值得一提的是 ,所有这些结果都是基于文中所示的简单结构而获得的。更多还原

【Abstract】 A very light weighted and extreme radiation hardness high doping n + i p + (sandwich like structure) InP solar cell was developed. Its total thickness of epitaxial layer is only 0.22mm. It is more radiation hardened than any other structures so that it can provide the required output power for spacecrafts even after a decade at 3200km polar orbits. The calculation demonstrates that its EOL (end of life) efficiency would be about 10%(AM0,1Sun); its highest power/weight ratio is about 130W/g (only the weight of epitaxial layers are considered).The surprising is that all of these are obtained from a very simple structure.更多还原
