Patent number: 9243340Abstract: The present invention describes a method of producing a p-type light-absorbing semiconductor copper zinc tin selenide/sulfide (Cu2(ZnxSn2-x)(SySe1-y)4) (abbreviated CZTS) with electrochemical deposition. It can be used in the production of solar cell when combined with an n-type inorganic or an organic semiconductor layer. The present method comprises a one-step or a sequence of depositions using electroplating to fabricate a low-cost and large-area CZTS solar cell, without using expensive and complicated deposition techniques or highly toxic and flammable chemicals in the production process. The present method significantly reduces the cost and energy requirement for production of solar cell.Type: GrantFiled: February 12, 2014Date of Patent: January 26, 2016Assignee: NANO AND ADVANCED MATERIALS INSTITUTE LIMITEDInventors: Kam Piu Ho, Paul Kwok Keung Ho, Man Wah Liu, Ranshi Wang, Wai Chun Luk, Wing Ho Choi, Fulin Zheng, Kwong Chau Kwok, Mei Mei Hsu, Ivan Ka Yu Lau

Patent number: 9197355Abstract: Drop port based shared risk link group (SRLG) systems and methods assign SRLG information to drop ports in another level or layer of a network. Thus, drop side SRLG information can be shared between different networks or layers enabling a combination with line side SRLG information within a network to identify and prevent single points of failure across the networks. Typically, SRLG details are assigned to line ports (NNI ports) within a network and this information is not shared with external networks or network layers for routing a connection through the network and the external networks. By assigning SRLG details to a drop port, this information can be relayed between the network and the external networks and considered when planning a route through all of the networks.Type: GrantFiled: November 27, 2012Date of Patent: November 24, 2015Assignee: Ciena CorporationInventors: Gerard Leo Swinkels, David Man-Wah Yeung

Patent number: 9091425Abstract: The invention provides a heat-conducting and heat-dissipating nano-material, a method for preparation thereof and a heat-dissipating system. The method comprises the following steps: i) mixing a complex formed by a high molecular material and a substance having heat conduction and heat dissipation properties with tert-butyl acetate and 4-Chlorobenzotrifluoride, wherein the complex is of nano scale in particle size; and ii) placing a mixture obtained from step i) into water and stirring the mixture in water for a period of time to afford the heat-conducting and heat-dissipating material. Application of the heat-conducting and heat-dissipating material in a heat-dissipating system of LED light may simplify the manufacturing process, save raw materials used and reduce weight and size of heat sink of the heat-dissipating system.Type: GrantFiled: June 10, 2011Date of Patent: July 28, 2015Assignee: Green Formula LimitedInventors: King Sun Juy, Man Wah Hui
