Polarization effect of dye-sensitizers on the current density and photovoltaic efficiency of co-sensitized DSSCs using metal-free and metal-based organic dyes

Abstract Co-sensitization of metal-free (Eosin and Coumarin) and metal-based (N3 and N719) organic dye combinations were employed with $ TiO_{2} $ nanoparticles based photoanodes for the fabrication of dye-sensitized solar cells. The charge injection and oxidized dye regeneration process in mono and...

520			\|a Abstract Co-sensitization of metal-free (Eosin and Coumarin) and metal-based (N3 and N719) organic dye combinations were employed with $ TiO_{2} $ nanoparticles based photoanodes for the fabrication of dye-sensitized solar cells. The charge injection and oxidized dye regeneration process in mono and co-sensitized system were explored from the constructed energy level diagram using cyclic voltammetry analysis. Electrochemical impedance measurements were performed to determine interfacial charge transfer kinetics such as chemical capacitance, recombination resistance and electron lifetime. Current density–Voltage (J–V) characteristics resulted an improved efficiencies in co-sensitized DSSCs due to increased short circuit current density (Jsc). The studies on polarization effect was also evaluated using conductivity plot of impedance spectroscopy. Here, we report for the first time, the internal polarization of dye-sensitizers contributes a small current in the total obtained current density (Jsc) of a device besides the conduction current which enhances the PCE. Especially, high polarization effect of coumarin dye by its resonance polar structure increasing the conductivity in intermediate frequency region of conductivity plot and thus the current density gets enhanced. Improved efficiency of ~ 5.4% was realized in pure metal-based dye co-sensitization by its optimized electron concentration in CB $ TiO_{2} $ to balance charge injection and recombination.

The charge injection and oxidized dye regeneration process in mono and co-sensitized system were explored from the constructed energy level diagram using cyclic voltammetry analysis. Electrochemical impedance measurements were performed to determine interfacial charge transfer kinetics such as chemical capacitance, recombination resistance and electron lifetime.

The charge injection and oxidized dye regeneration process in mono and co-sensitized system were explored from the constructed energy level diagram using cyclic voltammetry analysis. Electrochemical impedance measurements were performed to determine interfacial charge transfer kinetics such as chemical capacitance, recombination resistance and electron lifetime. Current density–Voltage (J–V) characteristics resulted an improved efficiencies in co-sensitized DSSCs due to increased short circuit current density (Jsc). The studies on polarization effect was also evaluated using conductivity plot of impedance spectroscopy. Here, we report for the first time, the internal polarization of dye-sensitizers contributes a small current in the total obtained current density (Jsc) of a device besides the conduction current which enhances the PCE. Especially, high polarization effect of coumarin dye by its resonance polar structure increasing the conductivity in intermediate frequency region of conductivity plot and thus the current density gets enhanced. Improved efficiency of ~ 5.4% was realized in pure metal-based dye co-sensitization by its optimized electron concentration in CB $ TiO_{2} $ to balance charge injection and recombination.</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Subalakshmi, K.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Karl Chinnu, M.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Senthilselvan, J.</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of materials science</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1990</subfield><subfield code="g">30(2018), 1 vom: 09.

title_auth	Polarization effect of dye-sensitizers on the current density and photovoltaic efficiency of co-sensitized DSSCs using metal-free and metal-based organic dyes
abstract	Abstract Co-sensitization of metal-free (Eosin and Coumarin) and metal-based (N3 and N719) organic dye combinations were employed with $ TiO_{2} $ nanoparticles based photoanodes for the fabrication of dye-sensitized solar cells. The charge injection and oxidized dye regeneration process in mono and co-sensitized system were explored from the constructed energy level diagram using cyclic voltammetry analysis. Electrochemical impedance measurements were performed to determine interfacial charge transfer kinetics such as chemical capacitance, recombination resistance and electron lifetime. Current density–Voltage (J–V) characteristics resulted an improved efficiencies in co-sensitized DSSCs due to increased short circuit current density (Jsc). The studies on polarization effect was also evaluated using conductivity plot of impedance spectroscopy. Here, we report for the first time, the internal polarization of dye-sensitizers contributes a small current in the total obtained current density (Jsc) of a device besides the conduction current which enhances the PCE. Especially, high polarization effect of coumarin dye by its resonance polar structure increasing the conductivity in intermediate frequency region of conductivity plot and thus the current density gets enhanced. Improved efficiency of ~ 5.4% was realized in pure metal-based dye co-sensitization by its optimized electron concentration in CB $ TiO_{2} $ to balance charge injection and recombination.
