Method and tool to reverse the charges in anti-reflection films used for solar cell applications
Anti-reflection coatings are used to improve light gathering in solar cells. The most common coating currently in use is made from hydrogenated silicon nitride. This coating develops a positive charge because of the charge on a silicon-nitrogen dangling bond, known as K centers. This charge creates a barrier layer that reduces surface recombination...

Self-Aligned Fabrication of Silicon Heterojunction Interdigitated Back Contact Solar Cells
Silicon Heterojunction Interdigitated Back Contact (SHJ-IBC) Solar Cells have both emitter and base contacts on the rear of the substrate that are interlocked like the fingers of two clasped hands. SHJ-IBC cells are advantageous, providing higher energy conversion efficiency and simplifying the interconnection of cells within a solar module. However,...
