Silver nanowire/polyimide composite transparent electrodes for reliable flexible polymer solar cells operating at high and ultra-low temperature

Abstract

A high and ultra-low temperature resistant flexible polymer solar cell was produced using a silver nanowire and polyimide composite transparent electrode. The composite transparent electrode exhibited excellent opto-electrical properties and flexibility across a wide temperature range of −150 to 250 °C. It also demonstrated strong adhesion, good abrasion performance, and excellent thermal and chemical stability. The power conversion efficiency of the flexible polymer solar cell based on this film was comparable to the device based on a flexible indium tin oxide electrode, and is quite stable under a wide range of applied temperatures.
