“…In order to then efficiently trap light in the thin absorber layers, light scattering at rough interfaces is usually used and is typically introduced by utilizing surfacetextured substrates. However, it was also reported that TF-Si layers deposited on highly textured substrates can exhibit locally low quality material regions or 2D nano-porous phases, which lead to deterioration of the electrical performance of TF-Si p-i-n junctions [1][2][3][4][5][6][7]. To maximize TFSi devices efficiency, one has therefore to find the optimum trade-off between high electrical and optical performances.…”

“…[1][2][3][4] The random textures are realized on various materials including wet-chemically etched ZnO:Al layers and as-deposited grown SnO 2 and ZnO:Al layers. [3][4][5][6] As for all of these textures the spectral response of thin-film silicon solar cells remains significantly below the theoretical limits, several new light-trapping concepts have been investigated recently. Two promising concepts are (i) surface gratings which allow for a control of the scattering angles via discrete diffraction orders [7][8][9][10][11] and (ii) Ag nanostructures of radii above 100 nm which scatter incident light at high efficiencies and low absorption via localized surface plasmon polaritons.…”

We report on the fabrication and optical simulation of a plasmonic light-trapping concept for microcrystalline silicon solar cells, consisting of silver nanostructures arranged in square lattice at the ZnO:Al/Ag back contact of the solar cell. Those solar cells deposited on this plasmonic reflection grating back contact showed an enhanced spectral response in the wavelengths range from 500 nm to 1000 nm, when comparing to flat solar cells. For a particular period, even an enhancement of the short circuit current density in comparison to the conventional random texture light-trapping concept is obtained. Full three-dimensional electromagnetic simulations are used to explain the working principle of the plasmonic light-trapping concept.

“…Our previous results showed that B contamination decreased the intensity of (220) preferential orientation [15]. In fact, several reports showed that a (220) preferential orientation is very important for the enhancement of short circuit current density (J sc ) of µc-Si:H solar cells [16,17].…”

We studied boron (B) contaminations at the p /i interface in hydrogenated microcrystalline silicon (μc‐Si:H) p ‐i ‐n solar cells deposited in a single chamber system. We used secondary ion mass spectroscopy to measure B depth profiles in μc‐Si:H thin films with different crystalline volume fraction (Xc) and found that μc‐Si:H films with a higher Xc showed a less boron contamination than that with a lower Xc in the amorphous/microcrystalline transition region. Based on this result, we proposed an interface layer with a suitable high Xc inserted between p and i layers to reduce the contaminations and then improve the performance of μc‐Si:H solar cells prepared in the single‐chamber system. The solar cell experiments indeed showed that a suitable high Xc interface layer decreased the boron contaminations at the p /i interface. The solar cell efficiency was increased with an enhanced short wavelength response. Combined with the optimized high Xc interface layer, the high quality μc‐Si:H, and the light trapping effect of front electrode, a single‐junction μc‐Si:H solar cell with 6.3% (1.0 cm2) of conversion efficiency was made in the single‐chamber system. Using the improved μc‐Si:H solar cell as the bottom cell, we achieved a 10.05% (1.0 cm2) efficiency for an a‐Si:H/μc‐Si:H tandem solar cell (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
