A solar cell arrangement 14 comprises first and second parabolic mirrors 32, <B>34</B> which collect light and focuses the light into a beam of light (16). The first parabolic mirror 32 has an aperture 37 through which the beam of light 16 passes. A prism means 18 receives the beam of light 16 and causes light 20 to emerge from the prism means 18. Optical means 22 for example, a diffraction grating or a plurality of convex lenses, receive the light 20 from the prism 18 and causes light to emerge from the optical means <B>22</B> as light <B>24</B> with different wavelengths. A semiconductor means 26 has a plurality of p-n junctions 28 which have energy levels at light peaks of the light 24 arriving at the surface of the p-n junctions 28. |
