Low-temperature production of crystalline silicon: A more efficient low-temperature process uses a liquid-metal electrode for preparing crystalline silicon

摘要

CRYSTALLINE SILICON IS A VERY IMPORTANT RAW MATERIAL due to its use in semiconductor electronics applications such as computers. Another use for crystalline silicon is in solar cells that capture energy from the sun. Research has been ongoing to find ways to reduce the cost of solar cells to enable this form of energy to become more competitive. In a previous TLT article, work conducted to develop a solar coating or paint was described. Quantum dots prepared from cadmium sulfide and cadmium selenide were coated on titanium dioxide nanoparticles and applied to a conductive surface to form a solar paint. This more cost-effective approach produced a coating that converted solar energy to electricity and has potential to be commercialized.
