摘要：

Solar thermoelectric generators (STG) using cheap parabolic concentrators with high-ZT modules can be a cost-effective alternative to solar photovoltaics for micropower generation. A thermodynamic analysis is presented for predicting the thermal-to-electrical conversion efficiency for the generator. With solar concentration of 66x suns, a system efficiency of 3% was measured for a commercial Bi(2)Te(3) module with output power of 1.8 W. Using novel thermoelectric materials such as n-type ErAs:(InGaAs)(1-x) (InAlAs) (x) and p-type (AgSbTe) (x) (PbSnTe)(1-x) , a conversion efficiency of 5.6% can be achieved for a STG at 120x suns.
