Embodiment Construction

[0037] figure 1 A schematic diagram of an exemplary solar powered generator 100 that generates electricity from sunlight 109 is provided. The solar powered generator 100 includes an optional solar concentration system 101 , solar panels 102 and thermoelectric devices 103 . Generator 100 requires radiator 104 to operate. The radiator 104 may be provided as part of the solar powered generator 100 . Generator 100 generates electricity from both solar panels 102 and thermoelectric devices 103 . These sources are usually drawn to the same voltage, combined and coupled to the load.

[0038] Solar concentration system 101 may be any suitable device for concentrating sunlight. The solar concentration system 101 can provide low, medium, and high levels of solar concentration. A low degree is a convergence factor f ranging from about 2 to about 10. Moderate convergence is in the range of about 10 to about 100. Convergence factors over 100 are quite high. In the absence of solar...

Abstract

A solar powered generator (100) has thermoelectric elements adjacent to and below solar cells. Concentrated sunlight is provided. A heat sink (104), which can be variable in temperature or efficiency, is in contact with the cold junction (108) of the thermoelectric device (103). The thermal resistivity is designed in relation to the energy flux, whereby the thermoelectric device (103) develops a gradient of several hundred Kelvin. Preferably the solar cell comprises a high band gap energy semi-conductor. The generator (100) maintains relatively consistent efficiency over a range of cold junction (108) temperatures. The heat sink (104) can be a hot water system. High efficiencies are achieved using nanocomposite thermoelectric materials. Evenly but thinly dispersing the thermoelectric segments in a matrix of highly insulating material reduces the amount of material required for the segments without sacrificing performance. A unitary construction of the solar cell and thermoelectric elements provides further advantages.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of US Provisional Application 61 / 198,256, filed November 4, 2008, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to solar powered devices and methods of converting solar power into usable forms of energy. Background technique [0004] There is a long-standing recognition and continuing need for cost-effective renewable energy sources. To this end, great efforts have been made to develop cost-effective solar powered generators to harvest solar energy. A major focus of these efforts is the manufacture of high-efficiency and low-cost solar panels. [0005] Solar panels are photovoltaic devices designed to convert solar energy directly into electricity. Basic solar panel technology is based on p-n junctions. The difference in carrier concentration between the p-doped and n-doped regions of the semiconductor mat...
