In this article, ITO/Si heterojunction solar cell is fabricated in which ITO thin film is applied to the Si-based heterojunction solar cells as a function of hole-selective contact. Furthermore, by incorporating hydrogen into the near interface of the ITO/Si heterojunction, we obtained a significant enhancement of device performances.
In the case of front grids, the grid geometry is optimised such to provide a low resistance contact to all areas of the solar cell surface without excessively shading it from sunlight. Heterojunction solar cells are typically metallised (ie. fabrication of the metal contacts) in two distinct methods.
Then, as suggested by optical simulations, the same stack of tungsten-doped indium oxide (IWO) and optimized MgF 2 layers are applied on both sides of front/back-contacted SHJ solar cells.
A Heterojunction IBC cell is often abbreviated to HBC. A HBC structure has several advantages over conventional SHJ cells; the major advantage is the elimination of shading from the front grid, which improves light capture and hence short circuit current density .
