Recent advances and future prospects of high performance flexible organic/inorganic thermoelectric composite
Thermoelectrics can recover the waste heat, environmental heat or heats from different sources to electricity. Inorganic or metal thermoelectrics have higher ZT values and efficiency, but they also have high cost and rigid or bad mechanical properties, contained toxic or rare elements. Organic thermoelectrics have low cost, flexible mechanical properties, easy and quick forming, but they have much low ZT values and efficiency, compared with inorganic materials. The organic-inorganic composite thermoelectrics can benefit from both properties and are also extremely competitive for commercial applications. This review will focus on the organic-inorganic composite thermoelectrics and devices, as well as their challenges.
