Soft electronic devices require the use of a flexible, transparent supercapacitor (SC) because of its interesting features such as light-weight, environmental-friendliness, design compact and fabrication ease and etc. In this work, we demonstrate a low-cost, fabrication method of a symmetric, conducting polymer based flexible transparent conducting electrodes (TCEs), using wire bar coating technique. The surface morphology and optical properties of TCEs were studied using an optical microscope and UV-vis spectrophotometer. The as-prepared TCE shows a transparency of T550nm ~85% with sheet resistance of 28 Ω/□. The areal capacitance per electrode of the champion SC device was recorded at 4.2 and 4.7 mF cm−2 via cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) measurements, respectively. This device shows excellent mechanical stability with highest reported capacitance values so far, particularly in flexible and transparent supercapacitor. |
