Problems solved by technology

Traditional semiconductor nuclear batteries use single crystal semiconductor wafers or epitaxially grown single crystal semiconductors, and form planar barrier regions through doping or heterogeneous contacts. Not only the production cost is high, but the utilization efficiency of radiation sources is also very low, and the overall energy conversion efficiency Usually not more than 5%, can not meet the application of engineering
