Abstract

Herein, we designed and synthesized two new metal-free organic dyes CCC ((E)-2-cyano-3-(6-((E)-(9-ethyl-9H-carbazol-3-ylimino)methyl)-9-hexyl-9H-carbazol-3-yl)acrylic acid) and CTC ((E)-2-cyano-3-(4-((4-((E)-(9-ethyl-9H-carbazol-3-ylimino)methyl) phenyl)(phenyl)amino)phenyl)acrylic acid) of D-D-π-A (donor-donor/π-spacer-acceptor) architecture. N-hexyl carbazole and triphenylamine were introduced as a donor as well as π-spacer, N-ethyl carbazole as an additional donor and cyano acrylic acid as acceptor. To evaluate photovoltaic properties of dye-sensitized solar cells (DSSCs), their photophysical, electrochemical and theoretical calculations were performed. The overall conversion efficiencies of the sensitizers CCC and CTC were 3.12% and 2.63%, respectively. Upon co-sensitized with N719 dye, fabricated solar cell with CCC dye showed highest short circuit current density of 19.33 mA/cm², open circuit voltage of 0.745 V and fill factor of 0.473 resulting in highest power conversion efficiency (PCE) of 8.01%, which is higher than DSSCs based on individual dyes may be due to greater incident photon current conversion efficiency and broader visible light absorption.
