Patent number: 7871940Abstract: A silicon nitride thin film formation apparatus is provided for stationary and moving substrates and a process for forming such films. The process provides high uniformity of film thickness and film properties as well as a high deposition rate. The film properties are adequate for application as an antireflection layer or passivation layer in solar cell devices or as dielectric layer in thin film transistors. The apparatus includes a number of metal filaments. In the space within the formation apparatus opposite to the substrate with respect to the filaments, a gas dosage system is arranged at a predetermined distance of the filaments. The film formation apparatus for stationary substrates also contains a shutter to control the starting and ending conditions for film formation and to control the film thickness.Type: GrantFiled: March 3, 2005Date of Patent: January 18, 2011Assignee: Universiteit Utrecht Holding B.V.Inventors: Rudolf Emmanuel Isidore Schropp, Catharina Henriette Maria Van Der Werf, Bernd Stannowski

Publication number: 20080283120Abstract: The invention provides solar cells and methods of manufacturing solar cells having a Hetero-junction with Intrinsic Thin-layer (HIT) structure using an n-type multicrystalline silicon substrate. An n-type multicrystalline silicon substrate is subjected to a phosphorus diffusion step using a relatively high temperature. The front side diffusion layer is then removed. As a next step, a p-type silicon thin film is deposited at the front side of the substrate. This sequence avoids heating the p-type silicon thin film above its deposition temperature, and maintains the quality of the p-type silicon thin film.Type: ApplicationFiled: October 4, 2006Publication date: November 20, 2008Applicant: STICHTING ENERGIEONDERZOEK CENTRUM NEDERLANDInventors: Yuji Komatsu, Hanno Dietrich Goldbach, Rudolf Emmanuel Isidore Schropp, Lambert Johan Geerligs

Patent number: 7227078Abstract: The invention pertains to a solar cell unit comprising a back electrode, a photovoltaic (PV) layer, and, optionally, a front electrode, with part of the surface of the solar cell unit not generating any energy, characterised in that on at least a portion of the part of the solar cell unit which does not generate any energy a colouring layer is present, while at least a portion of the energy generating part of the solar cell unit is free of a colouring layer. Preferably at least 50%, more preferably, at least 85%, more preferably still, at least 90% of the energy generating part of the solar cell unit is free of a colouring layer. The solar cell unit may be either a wafer-based solar cell unit or a thin film solar cell unit. The colouring layer may be applied on, e.g., the optionally present grid and/or in the case of thin film solar cell units on the part of the surface of the solar cell unit which does not generate any energy as a result of the connection in series.Type: GrantFiled: September 5, 2001Date of Patent: June 5, 2007Assignee: Akzo Nobel N.V.Inventors: Gert Jan Jongerden, Erik Middelman, Eleonoor Van Andel, Rudolf Emmanuel Isidore Schropp, Paulus Marinus Gezina Maria Peters, Dinah Elisabeth Hesselink

Publication number: 20030178058Abstract: The present invention pertains to a solar cell unit comprising a back electrode, a photovoltaic (PV) layer, and, optionally, a front electrode, with part of the surface of the solar cell unit not generating energy, wherein at least part of the non-energy-generating part of the solar cell unit is provided with a coloring material, while at least part of the energy-generating part of the solar cell unit is free of a coloring material, the color of the coloring material being different from that of the solar cell unit. If so desired, part of the non-energy-generating part of the solar cell unit may be provided with a camouflage material. The present invention makes it possible to select the color impression of the solar cell unit and/or decorate the solar cell unit while the electrical output of the solar cell unit is not affected.Type: ApplicationFiled: May 29, 2003Publication date: September 25, 2003Inventors: Gert Jan Jongerden, Erik Middelman, Eleonoor Van Andel, Rudolf Emmanuel Isidore Schropp, Paulus Marinus Gezina Maria Peters, Dinah Elisabeth Hesselink

Patent number: 6613598Abstract: The invention pertains to a method of making a photovoltaic cell at least comprising the following layers in the following order: a first electrode layer, a transparent wide band gap semiconductor layer provided with a layer of a photosensitising dye or pigment which in combination with the semiconductor layer has the ability to spatially separate photogenerated electrons from their positive countercharges, a layer of an electrolyte, a catalyst layer, and a second electrode layer. The method is characterized in that the first electrode layer and the semiconductor layer and/or the second electrode layer and the catalyst layer are deposited on a flexible temporary substrate that is removed later on. The electrode or electrodes, which are deposited on the temporary substrate, are transparent. The invention allows the roll-to-roll manufacture of said photovoltaic cell while providing great freedom in selecting the processing conditions.Type: GrantFiled: January 29, 2001Date of Patent: September 2, 2003Assignee: Akzo Nobel N.V.Inventors: Erik Middelman, Rudolf Emmanuel Isidore Schropp, Joshua Samuel Salafsky
