Revival of silicon solar cells for space applications

空间应用极薄硅太阳能电池的研制。这些空间电池将包括过去20年来硅电池的许多重大改进，这些改进使地球太阳能电池的效率接近最大可能，成本降低了一个数量级。空间电池需要良好的耐辐射性，以提供良好的寿命末期性能。该项目将使用已被证明可为陆地电池提供高性能的光伏架构，开发具有极强光捕获能力和更高辐射耐受性的超薄硅电池，以提供高的寿命开始和结束效率。这些电池的成本将不到目前太空中使用的多结电池的5%。

Development of very thin silicon solar cells for space applications. These space cells will include many of the significant improvements in silicon cells of the last 20 years, which have allowed close to the maximum possible efficiencies and the order of magnitude decrease in cost of terrestrial solar cells. Space cells require good radiation resistance to give good end of life performance. This project will use photovoltaic architectures, proven to give high performance for terrestrial cells, to develop ultrathin silicon cells with extreme light trapping and improved radiation tolerance to give high beginning and end of life efficiencies. These cells will be less than 5% of the cost of multijunction cells currently used in space.
