Abstract

The equilibrium lattice properties, electronic and optical properties of LiRE₂Si₃ (RE = Nd, Sm, and Eu) compounds have been investigated. LiRE₂Si₃ compounds show strong absorption in the entire range of solar spectrum. The conversion efficiencies are 52.4, 70.2, and 63.9% for LiNd₂Si₃, LiSm₂Si₃, and LiEu₂Si₃, respectively. The efficiencies of LiSm ₂Si₃ and LiEu₂Si₃ are about twice of GaAs (34%), and they are three times higher than Si (20%). The presence of 4f shell and the unoccupied π* states enhance the electron transportation invoked by photon adsorption. The LiRE₂Si₃ compounds are the excellent candidates of photovoltaic materials so far.
