Preparation of TiO<inf>2</inf> nanoparticles by sparking technique for enhancing photovoltaic performance of dye-sensitized solar cells

© 2017, Springer Science+Business Media Dordrecht. The double-layer photoanodes fabricated from TiO 2 nanoparticles (np-TiO 2 ) and TiO 2 powder (P25) for dye-sensitized solar cells (DSSCs) are reported. The np-TiO 2 was deposited on FTO substrates by a sparking technique. The PT1 and PT2 DSSCs w...

The np-TiO 2 was deposited on FTO substrates by a sparking technique.

In this research, the PT1 DSSC with a 1 h sparking period has the highest efficiency of 3.62, 50.21% higher than that of the reference. The enhancement is explained by the increase of adsorption of dye molecules that lead to a remarkable improvement in short-circuit photocurrent (J sc ). The pore size distribution with increasing the film thickness played a role in the penetration of the electrolyte, dye molecules and effective surface area. Moreover, a decrease in the interfacial resistance was detected in the P25/np-TiO 2 double-layered photoanode, leading to fast charge transport and decreased charge recombination in DSSCs. 2018-04-25T06:57:13Z 2018-04-25T06:57:13Z 2017-08-01 Journal 15685675 09226168 2-s2.0-85012885365 10.1007/s11164-017-2881-z https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=85012885365&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/46580
