Novel approach towards optically active and hexagonal plate morphology of Zinc doped Perylene Tetra Carboxylic Di Anhydride composite for high photovoltaic and flexible supercapacitor performances

Abstract

This paper reports novel features like photo-voltaic and energy storage capacity as dual performance in Zinc-Perylene Tetra-Carboxylic Di-Anhydride (Zn-PTCDA) composite have synthesized via hydrothermal method. This follows escape-by-crafty mechanism chemical reaction that produces the orthorhombic crystal structure. The Morphology transformation from stacked pyramids of PTCDA into hexagonal plates and rod structures of Zn-PTCDA. The optical study suggest that Zn-PTCDA composite provide compelling evidence for the Dye sensitized solar cell (DSSC) with Power Conversion Efficiency (PCE) is lower 0.2 % due to charge carrier recombination and promote to utilize this as transport layer of any solar cell. The electrochemical performance of pure Zn-PTCDA exhibits capacitance retention of 44.2 % while Zn-PTCDA-Graphene Oxide (Zn-PTCDA-GO) has capacitance retention 84.5 % over 5000 Galvanostatic-Charging and Discharging (GCD) cycles. The best specific capacitance 561 F/g at 2 A/g along with discharge through light emitting diode (LED) illumination for 2–3 min and also excellent energy density 31.5 Whr/kg and power density 4.5 kW/kg values. The incorporation of Zinc into PTCDA dye demonstrates Metal Organic Frameworks can provide improvements in the performances of both supercapacitors and dye-sensitized solar cells. The integration of both can instant storage of converted energy is needed solution to solve energy demand in future.
