20140287583 | ELECTRICALLY CONDUCTIVE PASTE FOR FRONT ELECTRODE OF SOLAR CELL AND PREPARATION METHOD THEREOF - The present invention provides an electrically conductive paste for a front electrode of a solar cell and a preparation method thereof. The electrically conductive paste is composed of a corrosion binder, a metallic powder and an organic carrier. The corrosion binder is one or more glass-free Pb—Te based crystalline compounds having a fixed melting temperature in a range of 440° C. to 760° C. During a sintering process of the electrically conductive paste for forming an electrode, the corrosion binder is converted into a liquid for easily corroding and penetrating an antireflective insulating layer on a front side of the solar cell, so that a good ohmic contact is formed. At the same time, the electrically conductive metallic powder is wetted, and the combination of the metallic powder is promoted. As a result, a high-conductivity front electrode of a crystalline silicon solar cell is formed. | 09-25-2014 |
20140220732 | CONDUCTIVE PASTE FOR FRONT ELECTRODE OF SEMICONDUCTOR DEVICE AND METHOD OF MANUFACTURING THEREOF - The present invention provides a conductive paste characterized by a crystal-based corrosion binder being combined with a glass frit and mixed with a metallic powder and an organic carrier. Methods for preparing each components of the conductive paste are disclosed including several embodiments of prepare Pb—Te—O-based crystal corrosion binder characterized by melting temperatures in a range of 440° C. to 760° C. and substantially free of any glass softening transition upon increasing temperature. Method for preparing the conductive paste includes mixture of the components and a grinding process to ensure all particle sizes in a range of 0.1 to 5.0 microns. Method of applying the conductive paste for the formation of a front electrode of a semiconductor device is presented to illustrate the effectiveness of the crystal-based corrosion binder in transforming the conductive paste to a metallic electrode with good ohmic contact with semiconductor surface. | 08-07-2014 |
20140141562 | REACTION APPARATUS AND METHOD FOR MANUFACTURING A CIGS ABSORBER OF A THIN FILM SOLAR CELL - The present invention provides an apparatus and a method for manufacturing a CIGS absorber of a thin film solar cell. The apparatus includes a supply chamber configured to provide a flexible substrate coated with precursors. The apparatus further includes a reaction chamber coupled to the supply chamber for at least subjecting the precursors on the flexible substrate to a reactive gas at a first state to form an absorber material. Additionally, the apparatus includes a gas-balancing chamber filled with the reactive gas at a second state. The gas-balancing chamber is communicated with the reaction chamber for automatically updating the first state of the reactive gas to the second state. Moreover, the apparatus includes a control system to maintain the second state of the reactive gas in the gas-balancing chamber at a preset condition and to adjust the transportation of the flexible substrate through the reaction chamber. | 05-22-2014 |
