内嵌硅量子点，高效率太阳能电池新突破

    Natcore太阳能公司称，该公司一项超高效太阳能电池项目已获成功。
    该公司说，赖斯大学研已成功地将一个涂层硅量子点封装入二氧化硅。该方案由教授Andrew Barron带头，是一项全硅、高效太阳能电池串联发展的重要里程碑。 在二氧化硅中封装个纳米晶体硅个体 - 硅量子点是一项突破性的技术。
    现在，Natcore公司在全球范围内享有该技术专利权。公司将创建三维阵列，吸收比普通晶体硅波长更短的多层次光硅量子点。
    Natcore估计，堆积阵列将将在成本更低的情况下提高每瓦额外效率，太阳能电池串联效率可达30%。
    据Natcore，串联太阳能电池，目前旨在太空中使用，但地球上申请使用其上层需用“外星”半导体材料。但是，LPD高科技免除了昂贵技术的需求。

    A project to create a super efficient solar cell has proved successful, according to Natcore Solar.
The firm said that a research programme at Rice University has successfully encapsulated silicon quantum dots with a uniform coating of silicon dioxide.
    The programme, conducted by Professor Andrew Barron, is a major milestone in the development of an all silicon, highly efficient tandem solar cell, the company claimed.  Encapsulising individual silicon nanocrystals - quantum dots - in silicon dioxide is a breakthrough technology.
    Natcore has an exclusive worldwide licence for that technology. Natcore will now create multiple layers of silicon quantum dots in 3D arrays that will absorb shorter wavelength light than in ordinary bulk silicon.
    Natcore estimates that the stacked arrays will increase the efficiency at a lower cost per extra watt, with efficiency of over 30 percent for tandem solar cells being likely.
    According to Natcore, tandem solar cells are currently used in space applications but earth based appps need to use "exotic" semiconducting materials for the upper layers. But LPD tech eliminates the need for the expensive technology.
