SPECTRUM SPLITTING USING FRESNEL LENSES AND SEPARATE UTILIZATION OF PHOTOVOLTAIC - SOLAR HEAT ENERGY

摘要

PURPOSE: A method for utilizing concentrating solar energy is provided to prevent efficient reduction of a solar cell by eliminating thermal energy from the solar cell and to prevent life shortening of the solar cell due to heat. CONSTITUTION: Pieces(1100) of glass refract light. A minute prism is considerably refracted. Rays(1200) of short wavelength are gathered inside glass prisms of a saw blade shape. Waves(1300) of long wavelength are gathered in the edge of the glass prisms of the saw blade shape. The pieces of glass gather light at one point while performing a prism.
