Figure 1. Concept of spectral-splitting hybrid PV-thermal collector technology.

Caption

The solar spectrum is separated by an optical filter, and only part of the spectrum is sent to the PV cells for electricity generation. The rest of the spectrum, which cannot be utilized by the solar cells, is directed to a thermal absorber to generate thermal energy.
