Synthesis and characterization of quantum dots-doped mesoporous powders

先进机械材料有限公司（AM&M）成立于2005年，已迅速发展成为为太阳能电池板制造商提供细粉的主要国际供应商之一。根据最近的市场报告，太阳能设备的市场规模以每年30%的速度增长。多孔硅粉是AM&M公司的核心产品之一，已广泛应用于光伏板的防反射涂层。据估计，AM&M公司产品的全球市场规模超过800亿美元。然而，将太阳能转化为晶体硅的效率不到20%。将金属氧化物半导体量子点掺杂到多孔硅晶体中，可以提高将太阳光转化为电能的效率。目前的挑战在于将小颗粒掺杂到AM&M生产的介孔硅粉末中，这一过程成本高昂。

Advanced Machine and Materials Inc. (AM&M) was founded in 2005 and has quickly grown into one of major international suppliers for providing fine powders for solar panel manufacturers. According to the recent market report, the market size of solar- powered devices increases with the rate of 30% annually. One of AM&M's core products, porous silicon powders have been extensively used as anti-reflective coatings on PV panel. It is estimated that the global market size to AM&M's products is over $80 billion. However, there is less than 20% efficiency of converting solar energy to crystalline silicon. Doping metal oxide semiconductor quantum dots into porous silicon crystals demonstrates the increase efficiency at converting sunlight into electricity. Current challenge lies in the expensive processes of doping small particles into mesoporous silicon powders produced by AM&M.
