Transparent flexible thermoelectric material based on non-toxic earth-abundant p-type copper iodide thin film
Thermoelectric devices that are flexible and optically transparent hold unique promise for future electronics. However, development of invisible thermoelectric elements is hindered by the lack of p-type transparent thermoelectric materials. Here we present the superior room-temperature thermoelectric performance of p-type transparent copper iodide (CuI) thin films. Large Seebeck coefficients an...
متن کاملCa3AlSb3: an inexpensive, non-toxic thermoelectric material for waste heat recovery
Thermoelectric materials directly convert thermal energy into electrical energy, offering a promising solid-state solution for waste heat recovery. For thermoelectric devices to make a significant impact on energy and the environment the major impediments are the efficiency, availability and toxicity of current thermoelectric materials. Typically, efficient thermoelectric materials contain heav...
متن کاملn-type thermoelectric material Mg2Sn0.75Ge0.25 for high power generation.
Thermoelectric power generation is one of the most promising techniques to use the huge amount of waste heat and solar energy. Traditionally, high thermoelectric figure-of-merit, ZT, has been the only parameter pursued for high conversion efficiency. Here, we emphasize that a high power factor (PF) is equivalently important for high power generation, in addition to high efficiency. A new n-type...
متن کاملZintl phases for thermoelectric devices.
By converting waste heat into electricity and improving the efficiency of refrigeration systems, thermoelectric devices could play a significant role in solving today's energy problems. Increasing the thermoelectric efficiency (as measured by the thermoelectric material's figure-of-merit, zT) is critical to the development of this technology. Complex Zintl phases, in particular, make ideal cand...
متن کاملOxide Based Thermoelectric Materials for Large Scale Power Generation
The thermoelectric (TE) devices are based on the Seebeck and Peltier effects, which describe the conversion between temperature gradient and electricity. The effectiveness of the material performance can be described by its figure of merit, ZT, which is defined as ZT = T , where a is the Seebeck coefficient of the material, a is the electrical conductivity and K is the total thermal conductivit...
