Fraunhofer ISE, AMOLF unveil TOPCon solar cell based on metal nanowire grid front electrodes

The two research institutes used silver nanowire grids as an alternative to indium tin oxide for the cell's transparent electrodes. They claim this is the first time that a metallic nanostructure offers photonic gain in a solar cell. Researchers from Dutch research institute AMOLF and Germany's Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) have developed a tunnel oxide passivated contact (TOPCon) solar cell that utilizes silver nanowire (Ag NW) grids as transparent electrodes. Due to their optoelectronic and mechanical properties, Ag NW networks are considered a valid alternative ...
