Abstract

Dye-sensitized solar cells (DSSCs) were fabricated with Ag nanoparticle (NP)-embedded TiO₂ nanotube arrays by using UV irradiation. The energy conversion efficiency was increased from 4.64% to 6.14% by the Ag functionalization, a 32% enhancement, which is attributed to surface plasmon resonances present along the entire length of the TiO₂ nanotube arrays. Furthermore, the Ag NPs more effectively enhanced the energy conversion efficiencies in front-illuminated DSSCs than in back-illuminated ones.
