Disclosed is a solar battery module including: a solar battery cell; and a surface material laminated to cover a surface of said cell; wherein a photocatalyst layer is formed on said surface material. With this module, it is possible to prevent contamination to the surface material of a solar battery module and prevent loss of sunlight irradiation energy to the solar battery, and hence to maintain an electric generation power for a long time.

In an optical waveguide comprising a transparent cladding (1) filled with a transparent liquid core (2) having a higher refractive index than the cladding, a liquid consisting of an oligomer having a phosphazene skeleton, typically phosphazene oil is used as the core (2). The waveguide is well resistant to heat and weathering, ensures stable performance in a wide temperature range over a long period of time, and provides good light transmission in a wide wavelength range covering the UV, visible and IR spectra.
