Emitter Wrap-Through solar cell

Technical Report ·
DOI:https://doi.org/10.2172/10161986· OSTI ID:10161986

The authors present a new cell concept (Emitter Wrap-Through or EWT) for a back-contact cell. The cell has laser-drilled vias to wrap the emitter on the front surface to contacts on the back surface and uses a potentially low-cost process sequence. Modeling calculations show that efficiencies of 18 and 21% are possible with large-area solar-grade multi- and monocrystalline silicon EWT cells, respectively.
