  • Publication number: 20200211729
    Abstract: A conductive paste for use in a laser-induced pattern transfer printing process includes a conductive component; a glass component; and an inorganic vehicle, wherein the conductive paste exhibits a light reflectance of no more than 50% across a light wavelength range of about 800 to about 1300 nm and improving the transfer of the paste to the substrate. A process for laser-induced pattern transfer printing includes providing a first substrate comprising a recessed surface and a conductive paste disposed in the recessed surface; orienting the recessed surface of the first substrate toward a second substrate; irradiating the conductive paste with a laser, the laser configured to emit light having a wavelength between about 800 and about 1300 nm; and transferring the irradiate conductive paste from the first substrate to a surface of the second substrate.

  • Publication number: 20200058820
    Abstract: The invention relates to a method for making a HIT solar cell comprising the steps of providing a substrate wherein the substrate comprises amorphous layers on the surfaces of the substrate respectively, providing an electroconductive paste comprising as constituents metallic particles and a polymer system then applying the electroconductive paste to the substrate surface to obtain a precursor and finally heating the precursor through microwave radiation to obtain a solar cell.

  • Publication number: 20110059230
    Abstract: The present invention relates to a novel method for applying conductive structures on solar cells, a hot melt aerosol ink being atomised by means of an aerosol jet printing system and being discharged from the printing system in the direction of the solar cell, the printing system being heated at least partially in order to keep low the viscosity of the ink which is used. When impinging on the non-heated substrate (solar cell), the ink solidifies.
