Contact Resistance and Metallurgical Connections Between Silver Coated Polymer Particles in Isotropic Conductive Adhesives
Pettersen, Sigurd Rolland; Kristiansen, Helge; Nagao, Shijo; Helland, Susanne; njagi, john; Suganuma, Katsuaki; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2016)Recently, there has been an increasing interest in silver thin film coated polymer spheres as conductive fillers in isotropic conductive adhesives (ICAs). Such ICAs yield resistivities similar to conventional silver flake ... -
Controlling the Conduction Mechanisms in Isotropic Conductive Adhesives with Silver-Coated Polymer Spheres
Pettersen, Sigurd Rolland; Kristiansen, Helge; Redford, Keith; Helland, Susanne; Kalland, Erik; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2016)Replacing the silver flakes in conventional isotropic conductive adhesives (ICAs) with micron sized polymer spheres coated with tens to hundreds nanometer of silver (AgPS) drastically reduces the silver content required ... -
Electrical Characterization of Amorphous Silicon Nitride Passivation Layers for Crystalline Silicon Solar Cells
Helland, Susanne (Master thesis, 2011)High quality surface passivation is important for the reduction of recombination losses in solar cells. In this work, the passivation properties of amorphous hydrogenated silicon nitride for crystalline silicon solar cells ... -
Investigation of thermal transport in polymer composites with percolating networks of silver thin films by the flash diffusivity method
Pettersen, Sigurd Rolland; Nagao, Shijo; Kristiansen, Helge; Helland, Susanne; Njagi, John; Suganuma, Katsuaki; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2017)The flash diffusivity method, also known as laser flash analysis (LFA), is commonly used to obtain the thermal diffusivity (α) and thermal conductivity (κ) of materials, due to its relative simplicity, rapid measurements, ... -
Room-Temperature Curing and Grain Growth at High Humidity in Conductive Adhesives with Ultra-Low Silver Content
Pettersen, Sigurd Rolland; Redford, Keith; njagi, john; Kristiansen, Helge; Helland, Susanne; Kalland, Erik; Goia, Dan; Zhang, Zhiliang; He, Jianying (Journal article; Peer reviewed, 2017)Isotropic conductive adhesives (ICAs) are alternatives to metallic solders as interconnects in solar modules and electronic devices, but normally require silver contents >25 vol.% and elevated curing temperatures to achieve ...
