Abstract
Spectral splitting medium is very important in the solar energy spectral splitting PV/T system. Due to good thermal conductivity and modulable spectral radiation characteristics, CuS is proposed as an alternative nanofluid in a PV/T system. The selective absorption characteristic of CuS nanofluid is closely related to the optical constant, and the optical constant of CuS nanofluids were studied. The results show that the extinction coefficient, k of CuS nanofluids, is very small in the ultraviolet and visible light bands with the order of magnitude is 10-6, while the other peak is detected at 1530 nm in the near infrared region with an order of magnitude of 10-3. The better absorption characteristics in the near infrared band than in the ultraviolet and visible bands confirms that CuS nanofluid is suitable for spectral splitting PV/T system. These optical properties provide strong support for the wide application of CuS nanofluid in the spectral splitting PV/T hybrid technology.
