This paper analyzes radiation heat transfer in a solar collector with wavelength dependence for hybridization of photovoltaic and solar thermal power generation. Optical multilayer films with separate transmission and reflection wavelength regions are attached to a solar panel to realize the hybridization. The wavelength dependence of the reflectance of the multilayer, the absorptivity of the heat collector, and the wavelength dependence of the reflected light concerning the solar orbit are implemented. The unsteady temperature distribution of the heat collector is analyzed by coupled light ray tracing analysis and radiation heat transfer analysis. The temperature of the heat collector is affected by the wavelength limitation when the optical multilayer is attached to the solar cell. It was also confirmed that the temperature of the collector area increased even when the wavelength range is divided by the optical multilayer films.
