Organic electronics have attracted gradual interest since the commercialization of organic light-emitting devices (OLEDs) that are now broadening their shares in large-size television after innovating the information displays in mobile systems including smart phones and smart pads. In terms of energy domains, organic solar cells have been extensively studied and their efficiency is now approaching the regime of thin-film Si solar cells. Recently, keen interest has been paid to organic thermoelectric devices because of their potentials for flexible energy sources even at low temperatures. Of various organic materials, conducting polymers have been widely applied for organic thermoelectric devices. However, the strong acidity of conventional conducting polymers is a potential drawback for achieving stable and durable devices. In this presentation, we show organic thermoelectric devices with the acidity-controlled active layers and discuss their practical applications at low temperatures. |
