Wie sich das deutsche Energiesystem wandeln soll, ist Gegenstand intensiver aktueller Debatten. Das gemeinsame Ziel vieler Überlegungen ist die Erreichung von Netto-Null- Treibhausgas-Emissionen. Über die Geschwindigkeit und die geeigneten Technolo

The scale-up of hot-wire CVD of a-Si:H based solar cells requires knowledge of how gas supply and filament geometry affect the deposition process. In this paper we report the important role of gas supply configuration and how it affects the uniformit

Thermo-catalytic (TC) or hot-wire (HW) chemical vapor deposition (CVD) is a promising technique for growing amorphous and microcrystalline silicon films with improved stability and high rates. In this paper we report on the photovoltaic (PV) applicat

In this paper we report the synthesis of highly conducting doped hydrogenated micro-crystalline silicon films, prepared by Cat-CVD deposition using silane and trimethyl boron (TMB) with hydrogen dilution at substrate temperatures as low as 110°C, ha

We report on the growth of highly conducting p-μc-Si:H films by hot-wire CVD. A systematic variation of the doping gas (trimethylboron) ratio was first carried out. High dark conductivity, σD≈1.0 Ω−1 cm−1 and low activation energy of dark co

For the first time, we report on a-Si:H/a-Si:H tandem solar cells, entirely fabricated by hot-wire CVD. Until now, our effort to develop a-Si:H/a-Si:H tandem cells has resulted in a 7.0% initial efficiency. Two types of tunnel junction, n/sup +/-/spl

The effect of moderate hydrogen dilution of the process gas, F(H2)/F(SiH4) = 0 to 3, on the properties of amorphous silicon is discussed for material and solar cells deposited by Hot-Wire CVD. Dielectric properties were obtained from spectroscopic el
