Full-wave simulation is performed to obtain an optimum design for maximum light absorption. The nanorods, after being coated with a shell to form a p-n junction, or being imparted with a radial junction, are of interest for enhanced light harvesting in solar cells, for example. The fabrication method of such arrays is described. Modeling of the spectral properties using equivalent circuit theory is implemented to predict fabrication results and provide an intuitive approach regarding the design of these optical metamaterials with predetermined properties.

  • Patent number: 8865251
    Abstract: The present invention relates to a metal nanobelt and a method of manufacturing the same, and a conductive ink composition and a conductive film including the same. The metal nanobelt can be easily manufactured at a normal temperature and pressure without requiring the application of high temperature and pressure, and also can be used to form a conductive film or conductive pattern that exhibits excellent conductivity if the conductive ink composition including the same is printed onto a substrate before a heat treatment or a drying process is carried out at low temperature. Therefore, the metal nanobelt and the conductive ink composition may be applied very appropriately for the formation of conductive patterns or conductive films for semiconductor devices, displays, solar cells in environments requiring low temperature heating. The metal nanobelt has a length of 500 nm or more, a length/width ratio of 10 or more, and a width/thickness ratio of 3 or more.

  • Publication number: 20140287583
    Abstract: 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.
