Abstract
Nowadays solar energy is expected to be a candidate to substitute for fossil fuels. This study aims at developing hybrid solar system to supply high temperature heat (100℃∿150℃) as well as electricity. The system consists of dye-sensitized solar cells and solar heat collector with Non-imaging fresnel lenses. Dye-sensitized solar cells use the radiant light to generate electricity. The infrared rays passing through the solar cell are collected onto absorber by Non-imaging flat flesnel lenses. The two kind of dye-sensitized solar cells are examined to estimate collectable energy with different transparency due to dye amount. The ratios of heat penetration of the cells are 40.7% and 27.2% under actual sun. The study also designed a solar heat collector with Non-imaging flat Fresnel lens mounted on a vacuum tube. The seasonal efficiency of heat absorption estimated taking collector angle adjustment into account.
