ABSTRACT
In this study, ultra-flexible organic photovoltaics (OPVs) with a new device structure are developed as a power source for ultra-flexible wearable devices with excellent biocompatibility. To fabricate ultra-flexible OPVs with excellent mechanical properties, we develop an ultra-flexible substrate with a bilayer structure based on polymers and transparent conducting oxides. An amorphous perfluorinated polymer (cyclic transparent optical polymer, CYTOP) is introduced as an ultra-flexible substrate by a solution process. An indium zinc tin oxide (IZTO) transparent electrode possessing an amorphous structure is fabricated via pulsed DC magnetron sputtering at room temperature using a target containing 80 atom % In2O3-10 atom % ZnO-10 atom % SnO2. Ultra-flexible OPVs with a one-dimensional (1D) grating pattern are fabricated on the buffer layer and photoactive layer. These OPVs exhibit an increase of 12% in power conversion efficiency (PCE) (maximum PCE 8.52%) compared to the reference, thereby minimizing reliance on the incident angle of light. In addition, even after 1000 compression/relaxation tests with a compression strain of 33%, the PCE of the ultra-flexible OPVs is maintained up to 94.8% of its initial value.
