The paper presents results of research on a new type of copper component that enables the production of Cu paste. Two pastes were applied during investigations: 1 – Pv19B commercial paste manufactured by Du Pont, 2 – experimental containing more than 50 % copper. Investigations were made into electrical properties of solar cells, with front metallization made in a non-conventional way (using template/stencil) on computerized Solar-Lab positioning table and included the measurement of I-V curves of the photovoltaic solar cells. The specific contact resistance of front metallization of the solar cell was measured also onto measuring position Corescan. Using the presented results, we can reduce the cost of silicone metallization by 50%, replacing the previously used silver with cheaper copper (CuXX).Keywords: Copper, screen-printing, photovoltaic cells, metallization, silver
