Patent number: 8796536Abstract: Provided are novel building integrable photovoltaic (BIP) modules that are mechanically and electrically interconnectable. According to various embodiments, the modules include channels and protrusion members. A channel of one module snugly fits over a protrusion member of an adjacent module to provide a moisture seal and, in certain embodiments, to collect water in between two modules and direct it downward. In certain embodiments, a channel is configured to interlock with a protrusion member in one or more directions. The channel is positioned along one edge of the module, while the protrusion member is positioned along the opposite edge, so that BIP modules can form a continuous interconnected row. The channel and protrusion member include electrical connectors having conductive elements. Inserting a protrusion member into a channel and, in certain embodiments, sliding one with respect to another also electrically interconnects the conductive elements.Type: GrantFiled: March 8, 2011Date of Patent: August 5, 2014Assignee: Hanergy Holding Group LtdInventor: Adam C.

Patent number: 8796542Abstract: An encapsulant material with enhanced light reflectivity, a crystalline silicon photovoltaic module and a thin film photovoltaic module are provided. The encapsulant material has a porous structure therein, and an average pore diameter of the porous structure is between several hundreds of nanometers and several hundreds of micrometers, so that the light reflectance of the encapsulant material is improved. Moreover, the encapsulant material is crosslinked by a physical or chemical crosslinking method, so heat resistance thereof is improved. Therefore, the encapsulant material is suitable for the crystalline silicon photovoltaic module and the thin film photovoltaic module, so as to increase power conversion efficiency of these modules.Type: GrantFiled: September 9, 2009Date of Patent: August 5, 2014Assignee: Industrial Technology Research InstituteInventors: Lee-May Huang, Cheng-Yu Peng, Wen-Chung Liang, Chun-Heng Chen
