美国Natcore Technology Inc.近日宣称在研发一种激光加工技术,以替代太阳能电池工艺中的高温扩散炉。该企业认为该计划有望削减与扩散炉相关的能源与化学材料的成本。Natcore表示正收购一种激光技术,供旗下位于纽约州罗切斯特市的研发中心使用。Natcore指出,激光掺杂的工作原理主要是在硅片上发射聚焦激光束。起初,只有少量的掺杂物落于表面。随后,激光束溶化于硅中,重新凝固。微秒的过程具有足够的时间来完成掺 US Natcore Technology Inc. recently announced that it is developing a laser processing technology to replace the high temperature diffusion furnace in solar cell technology. The firm believes the plan is expected to cut the cost of energy and chemical materials associated with diffusion furnaces. Natcore said it is acquiring a laser technology for use at its R & D facility in Rochester, NY. Natcore pointed out that the principle of laser doping works mainly focused on the silicon laser beam emitted. At first, only a small amount of dopant fell on the surface. Subsequently, the laser beam is dissolved in silicon and resolidified. The microsecond process has enough time to complete the doping
