Efficient renewable energy harvesting and storage are needed for present challenges related to clean environment and increasing energy demand. Different types of energy harvesting technologies such as solar, thermal and wind require excess energy to be stored in batteries, which further adds to the complication and increase in cost to the overall renewable energy system. Integrating the generation and storage of solar energy in a single device would be a more cost effective way towards meeting the increasing energy demand due to its simplicity in design and less space consumptions. Herein, a sustainable photovoltaic cell integrated with an energy storage device was developed that addresses short term photovoltaic (PV) power variability using dye sensitized solar cell (DSSC) in a tandem structure with thin film based lithium-ion battery. As lithium based batteries have been addressed as efficient charge storage system due to its high energy storage density and extended lifecycle performance. The integrated structure uses a common anode (titanium foil coated with anatase TiO2 on both sides which serves as DSSC and lithium ion battery anode) which showed an open-circuit voltage of ~3 V, a short circuit current density of ~40mAhg-1 and a storage efficiency of ~0.80%. This new device can serve as power source to mobile storage applications.
