Supercapacitors: An Efficient Ultra‐Flexible Photo‐Charging System Integrating Organic Photovoltaics and Supercapacitors (Adv. Energy Mater. 20/2020)

In article number 2000523, Kenjiro Fukuda, Takao Someya and co-workers integrate flexible organic photovoltaics with a carbon nanotube/polymer-based supercapacitor on a 1-µm-thick ultrathin substrate, enabling an efficient and ultra-flexible design. It exhibits a total system efficiency approaching 6% and a thickness below 50 µm, and a superior 94.66% efficiency retention after 5000 bending cycles at a radius of around 2 mm.
