    • 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.
