A Polymer Supercapacitor Capable of Self-Charging under Light Illumination

摘要

A novel transparent supercapacitor with a photoaotive layer and a capacitive structure integrated into one device is presented here. This device has achieved the combined abilities of self-charging under illumination and self-storage of photogenerated electrical signals. The photogenerated current density is About 2 mA g(-1). The specific capacitance is about 140 F g(-1). Its photogensing can function without an external, Was voltage given by a heavy per source, so it has great potential to he integrated into portable equipment. Moreover, this device can be easily assembled through a packaging-free process by using all-solid-state get electrolytes.
