Mg-La Co-Doped TiO2 as Compact Layer for High Efficient Dye-Sensitized Solar Cells

A compact layer of TiO2, between FTO and mesoporous TiO2 layer of DSSC anode, has the ability to reduce the electron recombination while mesoporous TiO2 layer functions to collect and transport electrons injected by the photoexcited dye. In enhancing the desired functions of compact and mesoporous T...

Summary:A compact layer of TiO2, between FTO and mesoporous TiO2 layer of DSSC anode, has the ability to reduce the electron recombination while mesoporous TiO2 layer functions to collect and transport electrons injected by the photoexcited dye. In enhancing the desired functions of compact and mesoporous TiO2, we study the effects of co-doping it with Mg, Eu, and La. MgLa co-doped TiO2 as compact layer has demonstrated higher efficiency due to its increased oxygen vacancies and smaller particle size which results reduced recombination. The combination of pure and co-doped TiO2 nanoparticles to be selected as either compact or mesoporous layer of DSSC anode depends on their respective properties, as demonstrated in this paper.
