Resumen
BALTAZAR VERA, J. C. et al. Energy response of dispersed red 1 azo dye mixed with reduced graphene and graphene oxide in sensitized solar cells. Acta univ [online]. 2018, vol.28, n.3, pp.9-16. ISSN 2007-9621. https://doi.org/10.15174/au.2018.1469.
Solar cells sensitized with an azo dye (dispersed red 1) mixed with graphene and graphene oxide by the electrophoresis method in acid medium applying a voltage of 3V at a time of 15 seconds were developed, these conditions allowed to deposit the layer satisfactorily semiconductor and subsequently properly confine the sensitizer. All cells were thermodynamically stable. The cells sensitized with disperse red 1 and disperse red 1 mixed with graphene and graphene oxide reported overall efficiencies of 0.12, 0.34 and 0.21 respectively. The maximum power calculated from the measured current density and voltage data for cells sensitized with dispersed red 1 and disperse red 1 mixed with graphene and graphene oxide were 9.68 W/cm2 x 10-3 W/cm2, 11.74 W/cm2 x 10-3 W/cm2, and 19.19 W/cm2 x 10-3 W/cm2 respectively. All photoelectrodes had stable confinement between the sensitizer and the semiconductor phase.
