CdTe photoelectric material with one-dimensional nanostructure and Bi2Te3 thermoelectric material were successively grown on FTO substrate by magnetron sputtering method for forming FTO/CdTe/Bi2Te3 heterojunction thin film. Whereafter, a power device was prepared by processing Ag electrode. The property of the device with light and heat synergy response was characterized by the V-t curve, which was collected through the circuit and optical path design. With the time difference between light and heat response, the curve of voltage-time was collected under the different light source, electrode contact point and light illumination direction. Meanwhile, the phenomenon of light and heat synergy response was identified with the illumination intensity of halogen and xenon light changeable. The results show that the synergy of photoelectric material and thermoelectric material in a single cell of CdTe/Bi2Te3 heterojunction can realize the light and heat synergy response, and it is anticipated to harvest solar energy from a wider solar spectrum.
