The influence of size on band gap was explored, and the results suggest that for semiconductors with narrow and moderate band gaps, the band gap increases as the size decreases. When the size of the particle decreases, the spaces between the bands get wider due to the lattice parameters rise as the diameter gets smaller.Jul 1, 2022 · Lower is the band gap of the absorber material, higher is the percentage of incident photons it can absorb.
