Cesium tungstate powder, or Cs0.33WO3, is often used as a near-infrared shielding material for production of coating glass - an energy efficient glass. Also, Cs0.33WO3 nanomaterial is capable of enhancing the output of thermoelectric (TE) conversion in an ambient environment. In this regard, some experts investigated the capability of Cs0.33WO3 nanomaterial in enhancing the output of a TE device by trapping the absorbed heat at the hot-side surface of the device.

In this process, the experts assessed the photothermal property of Cs0.33WO3 nanomaterial, in the form of solution or solid film, to gain better insight into its effects on the electrical output of the TE device, utilizing a laser with wavelength of 808 nm, a solar simulator, and sunlight in ambient environment. Moreover, they evaluated the photoelectric property of the Cs0.33WO3 nanomaterial-incorporated TE device in four different types of weather condition, sunny, sunny with partly cloudy, cloudy, and rainy. The results indicate that, in a complete sunny day, when compared with a bare thermoelectric device, the coating of Cs0.33WO3 nanomaterial with concentration of 0.66wt% demonstrated a rise of 13.1% in the maximal attainable temperature and a corresponding increase of 291% in maximal output voltage.
