We present an investigation on a power pack combining a CH3NH3PbI3-based solar cell with a polypyrrole-based supercapacitor and evaluate its performance as an energy pack. 3 billion by 2022, growing at a CAGR of 28. Supercapacitors are useful for a variety of power-stabilizing applications like backup systems and power buffers. 3V, 5V, 12V, etc. The AAT4620 also features a quiescent current of 40 μA typical, which drops to 1 μA in shutdown mode. ture for supercapacitor-based power supply is the one shown in Fig. The DC to DC power supply used to float and recharge the Supercapacitor is powered by a 24 or 48 Vdc load battery bank. Prior to low-impedance supercapacitors, designers needed to size the entire power supply system for the load's peak power. As of 2010, the best ultracapacitors can only store about 5% of the energy that lithium-ion rechargeable batteries can, limiting them to a couple of miles per charge.
