Temperature dependence of the optical absorption coefficient of microcrystalline silicon

The optical absorption coefficient of amorphous and microcrystalline silicon was determined in a spectral range 400-3100 nm and a temperature range 77-350 K. Transmittance measurement and Fourier transform photocurrent spectroscopy were used. The measured ...

Material and Solar Cell Research in Microcrystalline Silicon

Arvind Shah

This contribution describes the introduction of hydrogenated microcrystalline silicon (μc-Si:H) as novel absorber material for thin-film silicon solar cells. Work done at IMT Neuchâtel in connection with deposition of μc-Si:H layers by very high frequency ...

Thin film silicon solar cells for space applications: Study of proton irradiation and thermal annealing effects on the characteristics of solar cells and individual layers

Arvind Shah

The paper reports on the effects of a proton irradiation campaign on a series of thin-film silicon solar cells (single- and double-junction). The effect of subsequent thermal annealing on solar cells degraded by proton irradiation is investigated. A low-te ...

L'oxyde de zinc par dépôt chimique en phase vapeur comme contact électrique transparent et diffuseur de lumière pour les cellules solaires

Sylvie Faÿ

Zinc oxide (ZnO) is a material that belongs to the family of Transparent Conductives Oxides (TCO). Its non-toxicity and the abundant availability in the Earth's crust of its components make it an ideal candidate as electrical transparent contact for thin-f ...

Microcrystalline/Micromorph Silicon Thin-Film Solar Cells Prepared by the VHF-GD Technique

Arvind Shah, Sylvie Faÿ

Hydrogenated microcrystalline silicon prepared at low temperatures by the glow discharge technique is examined here with respect to its role as a new thin-film photovoltaic absorber material. XRD and TEM characterizations reveal that microcrystalline silic ...

Microcrystalline Silicon and Micromorph Tandem Solar Cells

Arvind Shah

'Micromorph' tandem solar cells consisting of a microcrystalline silicon bottom cell and an amorphous silicon top cell are considered as one of the most promising new thin-film silicon solar-cell concepts. Their promise lies in the hope of simultaneously a ...

Thin Film Silicon Solar Cells: A Review and Selected Trends

Arvind Shah

A case is developed for considering silicon as the prime medium-term candidate for semiconductor photovoltaic cells; the reason is based on other materials not being abundantly available, highly toxic, or very expensive. Crystalline silicon solar cells, ho ...
