Solar fluxes for reliable manufacturing

Emil Otto offers a wide portfolio for soldering solar modules, tabber and stringer material and connecting cells. This includes fluxes, rinsing and cleaning agents as well as tubular solder.

The fluxes are No Clean products that are formulated to be halogen-free. All fluxes leave no sticky residues. Process tests with well-known machine builders from the stringer technology sector prove this. Furthermore, the activators are specially designed for high temperatures, which are required in the production of solar modules, without affecting the efficiency of the activators. This also applies to the actual application in particularly sunny and hot regions.

Flussmittel - der Schlüssel zu präzisem Löten und langlebigen Verbindungen

In the context of the global change towards renewable energies, the solar industry plays a central role. The focus is not only on the end products, but also on environmentally friendly production processes. Emil Otto supports this change by providing environmentally friendly solar fluxes that allow the sustainable and efficient production of solar modules.

Emil Otto’s specialized solar fluxes meet the demanding requirements of the solar industry. The fluxes are characterized by the highest quality and environmental friendliness and are ideally suited for the production of solar cells and modules.

In the solar industry, the efficiency and quality of production play a critical role. With the fluxes developed by Emil Otto, soldering processes can be optimized, particularly in the production of photovoltaic modules. Solar cells are usually made of silicon, which is connected to metal contacts. The right flux ensures stable and long-lasting soldered connections here, no matter where the module is later used.

Emil Otto offers a variety of solvent-free and halogen-free fluxes that meet the high standards of the solar industry. The fluxes ensure reliable metallization, which is essential for the function and lifespan of solar modules. The fluxes are solvent-free and halogen-free, making them an environmentally friendly choice for modern solar production. This is particularly important as solar energy is a sustainable source of energy. Environmentally friendly production processes underline this claim.

Emil Otto’s fluxes offer significant added value for the solar industry:

Efficiency

High wetting and excellent soldering results ensure stable connections and consequently a longer lifespan for solar modules.

Versatility

The fluxes are equally suitable for soldering solar modules as well as tabber and stringer material.

Environmental friendliness

Our products are halogen- and solvent-free. This protects both the environment and the health of employees.

Process stability

The high purity of the fluxes ensures that no impurities occur that could affect the function of the solar cells.

Optimal process solutions

Emil Otto fluxes can be used for both automated and manual soldering processes. They provide stable results at high temperatures and ensure excellent wetting of the surfaces to be soldered. The electrical contacts of the solar cells are thus permanently and reliably connected, resulting in higher energy efficiency.
