Wafer-Based Solar Cell

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.
