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.

先进机械和材料公司(AM&M)成立于2005年，现已迅速成长为为太阳能电池板制造商提供精细粉末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。作为AM&M的核心产品之一，多孔硅粉已被广泛应用于光伏面板的减反射涂层。据估计，AM&M产品的全球市场规模超过800亿美元。然而，将太阳能转化为结晶硅的效率不到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生产的介孔硅粉中的昂贵工艺。
