Flexible organic solar cells: Materials, large-area fabrication techniques and potential applications

Organic solar cells (OSCs) that converted sunlight into electricity have obtained numerous progress in the past two decades. With the efforts of developing new conjugated materials, the power conversion efficiencies (PCEs) of OSCs have realized over 18%, which are comparable with other types of solar cells. These great achievements enable OSCs to arrive at the key period toward industrial application. Flexibility is the main characteristic of...
