摘要：
An environmentally friendly LiI/ethanol/SiO2 based gel electrolyte was synthesized by adding SiO2 nanoparticles into optimized LiI/ethanol based liquid electrolyte and used in quasi-solid-state dye-sensitized solar cells (DSSC), an energy conversion efficiency of 6.1% has been achieved at AM 1.5 simulated sunlight (91.3 mW cm(-2)). It was revealed that this gel electrolyte afforded almost identical energy conversion efficiency of DSSC to the corresponding liquid electrolyte. This promising gel electrolyte will enable the fabrication of environmentally friendly quasi-solid-state DSSC free of solvent evaporation and leakage. (c) 2005 Elsevier B.V. All rights reserved.
