    • The invention relates to an electro-conductive paste comprising Ag nano-particles and spherical Ag micro-particles in the preparation of electrodes, particularly in electrical devices, particularly in temperature sensitive electrical devices or solar cells, particularly in HIT (Heterojunction with Intrinsic Thin-layer) solar cells. In particular, the invention relates to a paste, a process for preparing a paste, a precursor, a process for preparing an electrical device and a module comprising electrical devices. The invention relates to a paste comprising the following paste constituents: a. Ag particles, b. a polymer system; wherein the Ag particles have a multi-modal distribution of particle diameter with at least a first maximum in the range from about 1 nm to about less than 1 μm and at least a further maximum in the range from about 1 μm to about less than 1 mm; wherein the difference between the first and the further maximum is at least about 0.3 μm; wherein at least 50 wt. % of the Ag particles with a diameter in the range from 1 μm to 1 mm are spherical.
    • 本发明涉及在电极制备中特别是在电气装置中,特别是在温度敏感的电气装置或太阳能电池中,特别是在HIT(与本征薄膜的异质结)中,包含Ag纳米颗粒和球形Ag微粒的导电浆料, 层)太阳能电池。 特别地,本发明涉及糊料,糊料的制备方法,前体,用于制备电子器件的方法和包括电子器件的模块。 本发明涉及一种包含以下糊状成分的糊状物:a。 银粒子,b。 聚合物体系; 其中所述Ag颗粒具有至少第一最大值在约1nm至约小于1μm范围内的至少第一最大值的至少一个最大值的至少约1μm至约小于1μm的粒径分布。 毫米 其中所述第一和所述另外的最大值之间的差为至少约0.3μm; 其中至少50wt。 直径在1μm至1mm范围内的Ag颗粒的%为球形。
