We used a new method to make carbon catalyst counter electrodes for dye-sensitized solar cells (DSSCs) by coating a fluorine-doped tin oxide (FTO)-glass with carbon nanoparticles from an aqueous colloidal suspension of the blend of carbon nanoparticles (particle size ≪50 nm and surface area ≫ 100 m2/g ) and TiO2. Z-907 dye was used as the sensitizer. The electrolyte effects on device performance were...
A planar concentrating solar cell based on a highly transparent sol-gel concentrator, metallic mirrors, and double sided PV devices is described. Highly transparent silica glasses, synthesized by sol-gel polymerization of tetraethylorthosilicate (TEOS), accompanied with an Ag back reflector were used for concentrating sunlight. By using TEOS, hydrochloric acid, ethanol, and water as the precursors...
