Wavelength separating and light condensing type generating and heating apparatus

摘要

For generation of electric power and heating of an object, sun-light is divided into generating light and heating light, which are then condensed separately, whereby both the electric power generating efficiency and the heating efficiency are improved. In order to divide sunlight, it is desirable that a selective reflector adapted to reflect the light used for power generation and transmit the heating light, and it is further preferable that this reflector serves also as a power generating light condensing system.
