Well, transparent electrodes are perfect for increasing efficiency by increasing energy reaching the cells; many solar manufacturers still require a paste to carry a high degree of current without the need for transparency. We have a solution in the form of our Hybrid silver paste. This solar conductive ink has many advantages, including: Lower Needed Silver Load Conventional Silver pastes have a problem: they require a high load of silver (around 70% by weight) to carry the amount of current being produced. This means that silver paste pricing is volatile and high directly related to the market cost of silver. Our solution overcomes both the Price and thickness issue through the simple addition of our long thin Nano Silver Strands. With the addition of our silver strands to silver flake nanoparticles, we can bridge between the burlier silver flake. This combination maintains the ability to carry large degrees of current well reducing the amount of silver by weight required (down to 15% silver). Reduced Thinkness Meaning More Flexibility Conventional Silver pastes need to be applied relatively thick to ensure adequate contact of the silver nano particle in the paste. By adding our Nano Silver Strands, we can increase the amount of contact between the silver flake allowing for a thinner, more flexible electrode. More Economic More Versitile This combination of attributes means our silver paste will allow you to make better, more flexible panels at a far reduced cost.
Our flagship product Nano Silver Strands is a highly conductive material designed to replace silver nanowires and silver nanoparticles, enabling the creation of more durable, stable and cost-effective electronics. As a highly conductive material, Nano Silver Strands formulations can be printed, sprayed or deep coated as a very thin layer on substrate or used with resins, epoxies, paints or pastes. Durable: SilverStrands is a unique one dimensional nanostructure which makes the material incredibly durable and highly stable when exposed to thermal and electrical stresses. SilverStrands can be mixed with many solvents including water, IPA or Ethanol, and can be applied to/in plastics, glass, fabrics, resins, epoxies and other substrates in a variety of methods. Cost Effective: SilverStrands is very cost effective for inks and conductive pastes. Because of its open structure, much less silver is required to achieve the same conductivity/resistivity as traditional silver particles or flakes. Superior Conductivity: Compared to conductive carbon nanofibers, silver flakes or particles, a much smaller loading of SilverStrands can be added to an epoxy, resin or paint without significantly affecting the properties of the base material to achieve similar or superior conductivity/resistivity properties Silver Strands Specifications - Film sheet Resistance: < 0.1-200 Ohms/sq - Resistivity: 6X10-7Ω.cm (average thickness 400nm) - Film transparency: up to 80% (at 550nm wavelength) - Stability in air: < 20% change in sheet resistance (60 days with no protective coating) - Thermal Stability: 300 ºC for 1 hour - Solvent: Water, IPA, Ethanol (others available upon request) - Compatible Substrates: Plastic, glass, fabric and others (resins and epoxies) - Film flexibility: Bending radius of 5mm on plastic Sheet resistance and transparency vary depending on the requested process, solvent, and substrate.

Our Flagship Product, Nano Silver Strands dispersed in methanol solution. Add our strands to an ink, epoxy, adhesive, resin, or other material to add conductivity. Nano Silver Strands are inherently more stable and durable than their nanowire counterparts, flexible compared to ceramic conductive materials such as Indium Tin Oxide (ITO), and more conductive than carbon-based conductive materials. Nano Silver Strands are thermodynamically stable because their major surfaces crystal planes are in the lowest energy state, whereas silver nanowires are at the highest energy level. The unique crystal structure of Nano Silver Strands makes it durable under thermal, electrical and chemical stress.

Transparent, flexible, conductive inks and coatings. Transparent conductive ink allows innovations such as resilient folding phones, solar windows, more efficient solar panels, next to invisible RFID tags, and comfortable, flexible biosensors. We now add these particles to several different inks for different purposes. Our Conductive Transparent Ink is one of these, and you can see what the ink looks like and how it works in this
