Publication number: 20100200044Abstract: A solar energy conversion system is presented. The system comprises at least one waveguide arrangement having at least one light input respectively. The waveguide arrangement comprises a core unit for passing input solar radiation therethrough and a cladding material arrangement interfacing with the core therealong. The cladding material arrangement is configured as an array of spaced-apart solar cells arranged along the core unit and having different optical absorption ranges, such that an interface between the waveguide core and the cladding arrangement spectrally splits the photons of the input solar radiation by causing the photons of different wavelengths, while passing through the core unit, to be successively absorbed and thereby converted into electricity by the successive solar cells of said array.Type: ApplicationFiled: May 30, 2007Publication date: August 12, 2010Applicants: BAR ILAN UNIVERSITY, YEDA RESEARCH AND DEVELOPMENT COMPANY LTD., THE REGENTS OF THE UNIVERSITY OF CALIFORNIA.Inventors: Arie Zaban, David Cahen, Igor Lubomirsky, Oscar M.
