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.

A system is presented for collecting and concentrating light from a moving light source (e.g. the Sun). The system comprises at least one anamorphic optical element, defining an optical axis and a projection region and having a predetermined effective aperture which defines primary and secondary axes. The effective aperture is configured for collection of optical radiation arriving from a predetermined solid collection angle defining a first range of angles with respect to a plane spanned by said optical and primary axes. The anamorphic optical element is configured such that light passing through said effective aperture within a predetermined first range of angles within said predetermined solid collection angle is concentrated onto at least a part of said projection region. At least one receiver aperture is defined by at least a part of said projection region.

This invention provides a rechargeable cell comprising an electrode including: a plurality of porous clusters of silver particles, wherein each cluster includes: (a) a plurality of silver particles, and (b) crystalline particles of zirconium oxide (ZrO2), wherein at least a portion of the crystalline particles of ZrO2 is located in pores formed by a surface of the plurality of silver particles. Electrodes of the present invention catalyze the reduction of oxygen in alkaline solution. When the cell is charged, the silver in the electrodes can be oxidized to Ag2O and further to AgO. Upon discharge, the reduction of the oxidized silver results in additional available energy. This invention provides electrodes for use in rechargeable cells or batteries and methods of making thereof.
