“…In this regime, the dark conductivity of the a-Si:H layer was observed to increase abruptly by over 1 order of magnitude due to a significant phase transition. This phase transition represents μc-Si:H formation within the a-Si: H matrix, as has been observed by many other researchers [8,9]. Higher-bandgap a-Si:H variants would clearly be beneficial in the production of high-performance top cells, but film quality should also be considered concurrently.…”

“…This means that in all cases the crystalline fraction gradually increases during film deposition, which is well-known phenomena for nc-Si:H growth. 12,32 For the C-series, X c increases as σ rms increases, whereas for the D-series, X c decreases as σ rms increases. This implies that X c cannot be simply correlated to σ rms of the substrates only, but that other factors play a role as well.…”

Thin-film silicon solar cells are often deposited on textured ZnO substrates. The solar-cell performance is strongly correlated to the substrate morphology, as this morphology determines light scattering, defective-region formation, and crystalline growth of hydrogenated nanocrystalline silicon (nc-Si:H). Our objective is to gain deeper insight in these correlations using the slope distribution, rms roughness (σ(rms)) and correlation length (lc) of textured substrates. A wide range of surface morphologies was obtained by Ar plasma treatment and wet etching of textured and flat-as-deposited ZnO substrates. The σ(rms), lc and slope distribution were deduced from AFM scans. Especially, the slope distribution of substrates was represented in an efficient way that light scattering and film growth direction can be more directly estimated at the same time. We observed that besides a high σ(rms), a high slope angle is beneficial to obtain high haze and scattering of light at larger angles, resulting in higher short-circuit current density of nc-Si:H solar cells. However, a high slope angle can also promote the creation of defective regions in nc-Si:H films grown on the substrate. It is also found that the crystalline fraction of nc-Si:H solar cells has a stronger correlation with the slope distributions than with σ(rms) of substrates. In this study, we successfully correlate all these observations with the solar-cell performance by using the slope distribution of substrates.
