Flexible Silicon Infrared Emitter
Effectively passivating a silicon cell leads to higher open circuit voltages and high efficiencies necessary for various electronic applications. Surface passivation is relevant for thinner wafers where recombination at the surface dominates total recombination. Thinner wafers are necessary as the voltage increases as a function of the excess carrier...

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,...

Transparent Conductive Oxide
Silicon heterojunction (SHJ) technology can provide high solar cell efficiency and low cost in high volume manufacturing. Transparent conductive oxides (TCOs), a component in SHJ cells, can help achieve good conductivity and electrical contact with metals for transferring current. However, optimizing TCO layers in SHJ solar cells requires a tradeoff...
