Solamet® photovoltaic (PV) metallization pastes are advanced solar cell materials that deliver significantly higher efficiency and greater power output for solar panels. When screen printed onto the surface of solar cells, metallization pastes collect the electricity produced by the cells and transport it out. Have a question? Get in touch
The amount of silver and aluminum paste used in solar cells differs and is determined by: Whether the aluminum paste forms a grid or whole area contact Typical screen-printed contacts are usually 125-150 µm wide. Are there any other materials that do the same function? Yes, other materials can serve the same purpose as silver and aluminum paste.
This novel titania paste has been developed for screen printing of ultra thin mesoporous titanium dioxide scaffold layers for perovskite solar cells. A single layer printed with 150T or 180T mesh screens generates a film in the range of 300-400 nm thick with excellent uniformity and reproducibility.
The paste compositions are a series of screen printable front and back side silver conductors for monocrystalline and multicrystalline solar cells. Our compositions are all cadmium-free and tailored solutions for either SiNx or TiOx anti-reflective coatings. Lead-free formulations are also available.
