Lightweight carbon electrodes are the new candidates for photovoltaic devices due to their temperature resistivity, ease of fabrication, and skin comfortability. Herein, a sustainable and facile strategy has been proposed for metal free all carbon dye sensitized solar cell (C-DSSC), assembled by stacking carbon front electrode (CFE) and carbon counter electrode (CCE). The CFE demonstrated adequate light transmittance (70-50%) while maintaining efficient photon absorption and charge separation mechanism due to dye coated TiO2 nanorods (P25-R). The graphene dip coated carbon counter electrode (Gr@CCE) possesses remarkable electro catalytic activity towards I-3(-)/I- redox couple with low charge transfer resistance (R-CT = 0.79 Omega). The sustainable design of C-DSSC attained similar to 6 +/- 0.5% efficiency with high photocurrent density of 18.835 mA. cm(-2). The superior performance of C-DSSC is accredited to its improved charge mobility, low internal resistance, and better interfacial electrode contact. The thickness of C-DSSC is <= 3 mm eliminates the need for rigid glass in DSSC. (C) 2020 Elsevier Inc. All rights reserved.
