Plasma enhanced chemical vapour deposition (PECVD) of thin films such as amorphous silicon has widespread applications especially in the field of photovoltaic solar cells and thin-film transistors for flat screen production. Industrial applications require ...
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 ...
We have demonstrated an original approach for fabricating microcavities in GaN grown on Si. Holes are etched in the Si substrate and highly reflective dielectric mirrors are deposited on both front and back sides. The cavity has been optically characterize ...
Zinc oxide (ZnO) is now often used as a transparent conductive oxide for contacts in thin-film silicon solar cells. This paper presents a study of ZnO material deposited by the low-pressure chemical vapour deposition technique, in a pressure range below th ...
'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 ...
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 ...
This paper investigates the stability of dilution series of pin and nip microcrystalline silicon solar cells under low-energy proton irradiation (E = 405 keV). Variation of electrical parameters, defect-related absorption and Urbach parameter are investiga ...
Low pressure chemical vapour deposition (LP-CVD) ZnO as front transparent conductive oxide (TCO), developed at IMT, has excellent light-trapping properties for a-Si:H p-i-n single-junction and 'micromorph' (amorphous/microcrystalline silicon) tandem solar ...
Nanocrystalline semiconductor films are constituted by a network of mesoscopic oxide particles, such as TiO2, ZnO, Nb2O5 which are interconnected to allow for electronic conduction to take place. The pores between the particles are filled with a semiconduc ...
