    • 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.
    • 描述了用于形成光伏导电特征的光伏导电特征和工艺。 该方法包括(a)提供包括设置在硅层上的钝化层的衬底; (b)将表面改性材料沉积在所述钝化层的至少一部分上; (c)将包含至少一种包含金属或金属前体的金属纳米颗粒的组合物沉积到所述基底的至少一部分上; 和(d)加热组合物使得其形成与硅层电接触的光伏导电特征的至少一部分,其中组合物或表面改性材料中的至少一种蚀刻钝化层的区域。 当表面改性材料是可UV固化的材料时,该方法包括固化可UV固化的材料的附加步骤。
