Method of fabricating solar cells with silicon nitride coating

Abstract: A process of manufacturing silicon solar cells with efficiencies of between about 12.5 % and about 16.0 % is described, the method being characterized by forming a P/N junction (4) adjacent the front surface of a silicon substrate (2), subjecting the front surface of the substrate to a selected plasma surface etch treatment, and then forming a polysilazane coating (10) on the etched front surface by (a) first subjecting the substrate to an ammonia plasma treatment for a predetermined period of time so as to produce hydrogen implantation and (b) subjecting the substrate to a silane and ammonia plasma treatment to obtain additional hydrogen implantation and formation of a polysilazane (hydrogenated silicon nitride) coating. The polysilazane coating (10) is etched to form a grid electrode pattern (12A). An aluminum coating (14) is applied to the rear side of the substrate so as to form a back electrode. The exposed silicon on the front side of the substrate is coated with an adherent coating of a highly conductive metal so as to form a grid electrode (20).

Structuring and transfer zones in the Faeroe Basin in a regional tectonic context

Abstract: An integrated structural interpretation of the Faeroe Basin within the regional tectonic setting of the North Atlantic margin was derived from gravity, magnetic and regional seismic data. The tectonic framework of the basin was established during the Caledonian orogeny while its subsequent structural evolution was linked to the development of the Greenland–Scotland Ridge and the Iceland hot-spot. Some major transfer zones had previously been identified in the Faeroe Basin area. The gravity and magnetic data defined a series of transfer zones oriented NW–SE across the basin which were also identified on seismic data. These transfer zones have had major influences on the Mesozoic sedimentation patterns, and define basin segments which most likely had different sedimentary and structural histories, thus introducing a diversity of hydrocarbon plays into the Faeroe Basin.

Silica-modified catalyst and use for selective production of para-dialkyl substituted benzenes

Abstract: The present invention relates to selective conversion of certain hydrocarbon feedstocks to product rich in para-dialkyl substituent benzenes over a catalyst composition comprising a crystalline zeolite having deposited thereon a coating of silica which extensively covers and resides substantially exclusively on the external surface thereof.

Simultaneous hydraulic fracturing using fluids with different densities

Abstract: Two spaced apart zones of a formation are simultaneously hydraulically fractured. A lower density fracturing fluid is injected into an upper zone of the formation via an annulus of a perforated wellbore communicating with the upper zone thereby causing a fracture to propagate. Simultaneously therewith, a higher density fracturing fluid is injected into a lower spaced apart zone via a tube within the wellbore which fluidly communicates with the lower zone thereby causing simultaneously the propagation of a second fracture. Neither fracture contacts the other although complete fracture growth is obtained.
