The article offers the authors' insights on the potential use of emitter wrap through (EWT) technology, an industrial laser-based technology in the thin-film solar cells manufacturing industry. The authors say that EWT process improves solar cell efficiency and fast drilling rates by 60% of the laser pulse energy. Moreover, the authors conclude that temporal distribution of laser energy pulse can support EWT cost-efficiency.

    We performed two-dimensional technology computer-aided design simulations for interdigitated back contact (IBC) solar cells with rear trench structures (TS), denoted here as TS-IBC solar cells. First, we calculated a reference simulation model for conventional IBC solar cells. We then assumed a...

    The solar cell does not use a pn-junction to separate electrons from holes, but uses an undoped CdS layer that is p-type inverted when attached to a p-type collector and collects the holes while rejecting the backflow of electrons and thereby prevents junction leakage. The operation of the solar...
