仿生垛叠结构利用表面等离子共振效应增强染料敏化太阳能电池效率

he unique biological structures (stacking structure) in green leaves to exhibit an extremely high light-harvesting provide inspiration for the development of materials applied to DSSCs. Surface plasmon resonance (SPR) of Au nanoparticles and 3 dimensional structures of titanium dioxide electrodes are utilized to fabricate stacking structure photo anodes in plasmonic DSSCs for improving light-harvesting and conversion efficiency. The best efficiency (η) of electrode reaches 4.56% comparing with the pure titanium dioxide electrode (3.23%). A remarkable improvement of 48.5% and 41.2% in photocurrent generation and efficiency are achieved.
