Recent developments of silicon thin film solar cells on glass substrates

High-performance tandem silicon solar cells on F:SnO2

“…The i-layers consist of non-doped intrinsic amorphous and microcrystalline Si. These have different band-gaps and hence provide for a wider spectral response [1]. The doped layers are all made from μc-SiOx material, except for the top cell p-layer, which is a-SiC (due to the SnO 2 :F).…”

“…Transparent conducting oxides (TCOs) are widely used throughout industry and in particular in the production of solar cells where front electrical contacts are needed which are highly optically transparent and with a relatively low electrical resistance [1]. The properties of this TCO front contact have been shown to be critical to the performance of the thin film solar cells.…”

Growth, structure, and transport properties of thin (>10 nm) n-type microcrystalline silicon prepared on silicon oxide and its application to single-electron transistor

“…In contrast, it is thought that the growth of the randomly oriented c-Si:H is not affected by the growth surface structure under the deposition condition used because the perpendicular grain size of the c-Si:H measured by XRD (D 220 ) is much smaller than the film thickness and also smaller than those measured in the ͑220͒ or ͑400͒ preferentially oriented poly-Si. 3,37 This may result in a saturation of lateral and perpendicular grain size as well as Hall mobility observed in the c-Si:H films. As Kamiya et al report, the growth of the ͑400͒ oriented poly-Si depends significantly on the growth surface structure.…”

“…[1][2][3][4][5][6] Plasma-enhanced chemical vapor deposition ͑PECVD͒ is not only a common and simple technique employed in the fabrication of these silicon-based devices, it also provides the ability to control the film microstructure such as the grain size and the grain boundary structure. This feature makes it suitable for the development of materials for novel quantum effect devices such as single-electron transistors ͑SETs͒.…”

APCVD of dual layer transparent conductive oxides for photovoltaic applications

“…Transparent Conducting Oxides (TCO's) are widely used throughout industry and in particular in the production of solar cells where highly optically transparent and relatively low electrical resistance front contacts are needed [1]. The TCO properties are of high importance in the efficiency of the resulting PV cells.…”
