Hydrogenated amorphous silicon carbon films were grown by PECVD from silane/methane gas mixtures by fixing the methane ratio in the gas phase and by changing the rf power and pressure. The effects of the discharge parameters on the optical, electrica

Concentrating photovoltaics (CPV) represent an emerging market at its early stage for terrestrial application with large growth expectation and considerable research activity on new cell production has been conducting recently. In response to a fast

We report on the effect of the annealing temperature (range 600–1100 °C) on amorphous silicon-rich nitride films deposited by PECVD at 300 °C. The evolution of Raman spectra, room temperature photoluminescence, and optical absorption has been inv

Thin film photovoltaics is a particularly attractive technology for building integration. In this paper, we present our analysis on architectural issues and technological developments of thin film silicon photovoltaics. In particular, we focus on our

Micromorph tandem solar cells represent an elegant way of overcoming the efficiency limits of single-junction solar cells and reducing the light-induced degradation of amorphous silicon films. Micromorph devices have been realised on Asahi U-type TCO

Micromorph tandem solar cells have been realized growing the intrinsic layers of both amorphous silicon top cell and microcrystalline silicon bottom cell by VHF-PECVD at 100 MHz at low substrate temperature (150 °C). The influence of the microcrysta

We have realized micromorph tandem solar cells on Asahi U-type TCO-covered glass substrates. The intrinsic layers of both amorphous top cell and microcrystalline bottom cell are grown by very high frequency plasma enhanced chemical vapour deposition

Several series of microcrystalline silicon p-i-n solar cells were grown on glass substrates. The intrinsic layer of the devices was deposited by Very High Frequency Plasma Enhanced Chemical Vapor Deposition (VHF PECVD) at a frequency of 100 MHz. Vari
