Recent advancements in micro-crack inspection of crystalline silicon

The typical method of cutting silicon blocks to produce silicon wafers was previously based on the slurry wire-sawing technique, where the blocks are sliced by a smooth steel wire on which abrasive slurry is poured [29–32].This results in silicon wafers with relatively rough surfaces with consistent textural uniformity.

In 2011 Pi et al. spin-coated Si NCs onto screen-printed single-crystalline solar cells. The power-conversion efficiency (PCE) of the solar cell was increased by ∼4% after the spin-coating of Si NCs [34].Due to the anti-reflection effect of the Si-NC film, the reflectance of the solar cells was reduced in the spectral range from 300 to 1100 nm.

Smaller texture improves flexibility of crystalline silicon solar cells

When the thickness of c-Si wafers is thin enough, good flexibility will be gained [8], [9], but the indirect bandgap, the short optical path length of c-Si wafers and the parasitic absorption of amorphous silicon will result in inefficient light absorption of thin SHJ solar cells [10].The popular method to improve light absorption in c-Si is to form random micro pyramids
