In this paper, the effects of interrupted deposition of intrinsic hydrogenated amorphous silicon (i.a-Si:H) on the Si surface passivation are studied. Vibrational and optical properties of the i.a-Si:H films have been studied using Fourier transform infrared (FTIR) and Variable angle spectroscopic ellipsometry (VASE) respectively. The experiment confirms that the …

We investigated hydrogenated nanocrystalline silicon (nc-Si:H) films as doped emitter layers for silicon heterojunction solar cells. Firstly, we focused on the effect of the nc-Si:H deposition conditions and film growth on the intrinsic hydrogenated amorphous silicon passivation layer ((i)a-Si:H) underneath.

In all of the C/Si HJ solar cells mentioned above, the PCE and active area of the CNT/Si HJ solar cells has been greatly improved by using a "low-dimensional nanomaterials + organic passivation" strategy whilst at the same time reducing the complexity of fabrication in a CNT/Si HJ solar cell. The standard in-line process for the …

Silicon heterojunction (HJ) solar cells are one such passivated contact cell. HJ cells are typically formed with an n-type bulk between intrinsic amorphous silicon (a-Si) layers. The passivating contacts are then completed by a p-type doped a-Si layer for the hole contact and an n-type doped a-Si layer for the electron contact. As the lateral ...
