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 ...
Hydrogenated microcrystalline silicon i-layers were deposited with a fixed silane concentration on various substrates and incorporated into n-i-p solar cells. 'Average crystallinity' and detailed microstructure of layers and devices were evaluated by X-ray ...
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 ...
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 ...
Theoretical: Limits for Jsc, Voc, FF and efficiency of single-junction solar cells and tandems are derived, as a function of E g, showing that: (1) double-junction 'micromorph' solar cells constitute an optimum combination of bandgap values; (2) main futur ...
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 ...
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 ...
Intrinsic microcrystalline silicon opens up new ways for silicon thin-film multi-junction solar cells, the most promising being the "micromorph" tandem concept. The microstructure of entirely microcrystalline p-i-n solar cells is investigated by transmissi ...
Dye-sensitized nanocrystalline solar cells (DSC) have received considerable attention as a cost-effective alternative to conventional solar cells. One of the main factors that has hampered widespread practical use of DSC is the poor thermostability encount ...
