Fabrication of A-Si:H Solar cells on high haze SnO2:F thin films

In this work we report on the properties of amorphous silicon (a-Si:H) p-i-n solar cells fabricated on glass substrates covered with extremely high haze fluorinedoped tin oxide (SnO
2
:F) transparent conductive oxide (TCO) thin films, HU-TCO. The HU-TCO shows high haze value thorough the whole optical region where a-Si:H and microcrystalline silicon (μc-Si:H) solar cells are sensitive. We demonstrate here that open-circuit voltage (V
oc
) and fill factor (FF) of a-Si:H solar cells fabricated on HU-TCOs does not decrease significantly compared to the cells on conventional pyramidal texture TCOs. We also demonstrate here that V
oc
and FF of a-Si:H solar cells depend on not only surface morphology of TCOs, but also strongly depend on thickness and deposition conditions of the solar cells.
