ABSTRACT:
A combination comprises a device for receiving and for directing incoming light in a three dimensional manner to at least one predetermined location together with a solar cell. The device has two light reflecting surfaces and a total internal reflection surface. In operation, the total internal reflection surface transmits the incoming light into the device and totally internally reflects the light reflected from the surface which is incident at its surface at an angle within the range for total internal reflection. The reflection surfaces are operatively disposed with respect to one another so as to perform the function of a receiver/director by directing incoming light in a three dimensional manner to the rear surface of the solar cell.
