TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Method: The layer is chemically attached to the conducting glass surface. Prior to the disposing step, the method additionally involves contacting the conducting glass surface with a solution containing an additional organic titania precursor to produce a wetted conducting glass surface, where the surface is coated with titanium-containing species, which is chemically bound to the conducting glass surface. The disposing step is performed by screenprinting. The method additionally involves sintering the wetted titania coated conducting glass surface to produce a nanometric sintered layer of a titania derived from the additional portion of the organic titania precursor. The nanometric sintered layer has an average thickness of less than 200 (preferably less than 100, especially less than 50) nanometers. Subsequently to the step of producing the photoanode, the method involves contacting the sintered titania layer with a solution containing an additional organic titania precursor to produce a wetted titania sintered titania layer; and sintering the wetted titania coated sintered titania layer to produce resintered layer with an improved electrical conductivity related to the sintered titania layer.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The titania particles have particle size of below 30 (preferably below 20) nanometers. The titania precursors are selected from organic titanium chelates, aqueous titanium chelates, and ortho titanate ester). The precursor includes titanium chelate or titanium acetylacetonate. The weight ratio of organic, non-fuming titania precursor to the titania powder in the paste is 1-10 to 7-10 (preferably 2-10 to 6-10).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The liquid additionally includes at least one solvent, where the precursor is dissolved in the solvent; thickener (preferably dissolved ethyl cellulose); heat fugitive pore-forming material; alcohol; terpineol; and non-ionic surfactant (preferably acetone, especially acetyl acetone) chemically bound with the titania particles. EXAMPLE - A Tyzor AA-105 (RTM: titanium acetylacetonate) (20 g) was stirred into a solution of screenprinting vehicle terpineol containing dissolved Ethocel (RTM: ethyl cellulose) (2.5 wt.%) to form mixture (m1). Then acetyl acetone was mixed with isopropyl alcohol to give mixture (m2). Both mixtures (m1) and (m2) were mixed; and then Degussa type VP P90 (RTM: titania powder) (50 g) was added. The resulting titania paste was screenprinted onto an fluorine-doped tine oxide (FTO) glass by three printing and finally the printed layer was sintered at 450 degrees C air for 30 minutes. The sintered titania layer was coated with Solaronix SA (RTM: ruthenium dye sensitizer) and was assembled with a platinum-catalyzed FTO glass as the counterelectrode and formed three cells. The cell performance was tested in a solar simulator providing one sun illumination (100 mW/sq.cm). The averaged performance results of the three cells were: open circuit voltage of 704 mV; short circuit current of 15.3 mA/sq.cm; fill factor of 59.4%; and solar-to-electricity conversion efficiency of 6.27%.
