WebIn this work, ultra-thin n-type hydrogenated nanocrystalline silicon oxide [(nc-SiOx:H (n)] film was used to replace amorphous silicon [a-Si:H (n)] as electron transport layer (ETL) in rear-junction silicon heterojunction (SHJ) solar cell to reduce front parasitic absorption. The contact resistivity between the transparent conductive oxide (TCO) and ultra-thin ETL … WebTransparent conducting oxides (TCOs) used in solar cells must be optimized to achieve minimum parasitic absorption losses while providing sufficient lateral conductivity.
Web1 Jul 2013 · Consider a polished silicon solar cell with no antireflection coating; when averaged over the absorbed part of the solar spectrum (up to 1100 nm) and across all incident angles, ~37% of light is lost to reflection. Such high reflection arises from the mismatch in the refractive index between the air and the solar cell. WebIt is advantageous for the passivating layer to have a higher band gap in order to minimise parasitic absorption of photons, as absorption coefficient is partially dependent on band gap. Heterojunction cells are commercially mass-produced and are commonly bifacial.
