Processes for forming photovoltaic conductive features from multiple inks |
摘要 |
<p>Photovoltaic conductive features and processes for forming photovoltaic conductive features are described. The process comprises (a) providing a substrate comprising a passivation layer disposed on a silicon layer; (b) depositing a surface modifying material onto at least a portion of the passivation layer; (c)depositing a composition comprising at least one of metallic nanoparticles comprising a metal or a metal precursor to the metal onto at least a portion of the substrate; and (d) heating the composition such that it forms at least a portion of a photovoltaic conductive feature in electrical contact with the silicon layer, wherein at least one of the composition or the surface modifying material etches a region of the passivation layer. When the surface modifying material is a UV-curable material, the process comprises the additional step of curing the UV-curable material.</p> |
