Abstract Several techniques have been proposed for kerfless wafering of thin Si wafers, which is one of the most essential techniques for reducing Si material loss in conventional wafering methods to lower cell cost. Proton induced exfoliation is one

Dominant changes in structural, optical, and magnetic properties were observed at the highest dose of implanted ions with larger ionic radii which is due to the large number of produced defects in the host.

We report high efficiency cell processing technologies for the ultra-thin Si solar cells based on crystalline Si thin foils (below a 50 µm thickness) produced by the proton implant exfoliation (PIE) technique. Shallow textures of submicrometer scale

Si ions 2.3 MeV are implanted into nanodiamonds (NDs) at doses of 1×1012 ~ 1×1015 ions/cm2. The ion implantation not only creates silicon-vacancy (SiV) color centers but also reduces the size of the NDs from 50 nm to ~ 10 nm. As the Si dose is incr
