Turning water into a protonic diode and solar cell via doping and dye sensitization

ABSTRACTThe fabrication and testing of screen printed dye-sensitized large solar cell (15 cm × 15 cm) based on nanocrystalline TiO2 is described. It is the largest photo-electrochemical (PEC) cell that is based on the dye sensitization of thin (8-18 μm) films of TiO2 nanoparticles in contact with a non-aqueous liquid electrolyte. The cell has the potential to be a low cost, commercial, environmentally friendly, photovoltaic option. Surface as well as electrical characterization, of the nanostructured PEC cells have been performed. The efficiency of these large commercial cells are compared to the laboratory-made small PEC cells. Key words: Photoelectrochemical, solar cells, nanocrystalline, dye-sensitized

Photoelectrochemical Solar Cells

The development of thin-layer transparent solar cells based on dye sensitization of nanocrystallinen-typeTiO2undertaken at the Laboratory of Inorganic Photochemistry and Energy Conversion at the Chemistry Institute of Universidade de São Paulo is presented. Compounds of the formulacis-[(dcbH2)2RuLL],L,L′= substituted pyridines, as nanocrystallineTiO2,dcbH2=4,4′−(CO2H)2−2,2′-bipyridine andL,L′= substituted pyridines, have been successfully employed as molecular sensitizers in photoelectrochemical solar cells based on dye-sensitization ofn-TiO2. This regenerative solar cell consists of a TCO glass with a dye-sensitizedTiO2semiconductor film as a photoanode,I2/LiIsolution in acetonitrile as a redox mediator and a transparent Pt coated TCO glass as a counter electrode. Efficient conversion of visible light into electricity was achieved with IPCE (Incident Photon-to-Current Conversion Efficiency) as high as 50% between 400 and 550 nm.
