Webboron (p-type) dopant is susceptible to reaction of 10B nuclei with incident neutrons. Particles produced in the neutron capture reaction will then lose kinetic energy as they travel through the silicon substrate. This can produce electron hole pairs, and result in charge collection (Q coll). If Q coll exceeds the critical charge needed to ...

WebJul 6, 2024 · Boron is used for doping P-type solar panels, but they cause a problem known as a boron-oxygen defect (not a problem in space where there is no oxygen). This defect produces a high amount of Light-Induced Degradation (LID) in P-type solar panels, reducing their performance by up to 10% in some cases. WebThe P-type elements from group IIIA of the periodic table include boron, aluminum, gallium, and indium. Boron is used as a P-type dopant for silicon and diamond semiconductors, while indium is used with germanium.
