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 (ZrO), wherein at least a portion of the crystalline particles of ZrOis 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 AgO 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.

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.
