Abstract
A solar cell arrangement comprises a first plate or disc of light transmissive material, one side of the first plate or disc having a structure of light transmissive elevations tapering parabolically and cut off parallel to the surface of the plate or disc at the level of their focal points or lines, the structure having a layer of at least partially light transmissive electrically conductive material on the surface of the elevations and a second plate or disc of semiconductor or metallically conducting material, the plate or discs being assembled together to provide photo voltaic and electical contacts between the said cut off surfaces, of one plate or disc and the surface of the other plate or disc such that light passing through the first plate is concentrated at the contacts.
Claims18
A solar cell arrangement, in which two separate plates or discs are provided;
- one plate or disc comprises light-transmissive material;
- one side of this plate or disc has a regular structure of light-transmissive elevations which taper parabolically;
- these parabolic elevations are cut off parallel to the surface of the plate or disc at the level of their focal points or lines;
- the surface of the parabolic elevations is coated with an at least partially light-transmissive, electrically conductive layer;
- the second plate or disc of the arrangement comprises semiconductor or metallically conductive material;
- and both plates or discs are assembled mechanically so that the cut off surfaces of the parabolic elevations form photovoltaic or non-blocking electrical contacts with the surface of the semiconductor or metallically conductive plate or disc so that light which passes through the light-transmissive plate or disc is concentrated at the contacts.
A solar cell arrangement comprising a first plate or disc of light transmissive material, a structure comprising light transmissive elevations tapering parabolically on one side of said first plate or disc and cut off parallel to the surface of said first plate or disc at the level of their focal points or lines, a layer of at least partially light transmissive electrically conductive material on the surface of said elevations and a second plate or disc of semiconductor or metallically conductive material assembled to said first plate or disc to provide photovoltaic or electrical contacts between said cut off surfaces of said elevations of said first plate or disc with the surface of said second plate or disc whereby light which passes through said first plate or disc is concentrated at said contacts.
