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.
