We report on the performance of contact grids based on Ag, Al, and Au applied to III-V multijunction solar cells. We compare their their suitability as grid metals from different perspectives, including price, mass-to-conductivity ratio, and abundance. The grid functionality was evaluated by performing charge transport experiments under simulated sunlight. The best solar cell performance was obtained for Ag contacts. On the other hand, Al and Ag provide the most cost-effective approach: when compared to Au for equal conductivities, the cost for the grid material being only about 1.1% in the case of Ag, and 0.7% for Al.
