Latest Patents

Knight holds a patent for "Methods, apparatus, and systems for passivation of solar cells and other semiconductor devices." This patent describes a method of passivating semiconductor devices using existing tools of junction isolation and phosphosilicate glass (PSG)/borosilicate glass (BSG) etch via room temperature wet chemical growth (RTWCG) processes. The method allows for back side processing of the semiconductor device to achieve passivation and junction isolation in a single step. Additionally, front side processing achieves passivation, PSG/BSG etch, anti-reflection coating, and potential induced degradation (PID) mitigation simultaneously. The integration of this passivation formation method into conventional solar cell manufacturing systems results in solar cells that feature a semiconductor substrate with a front surface coated with a SiOx layer less than 50 nm thick, over which a SiNx layer is deposited. The back surface is also coated with another SiOx layer. Experimental data indicates that these solar cells exhibit high efficiency and mitigated PID.
