摘要: We report the theoretical efficiency of thermoelectric power generation with asymmetric thermal contacts to reservoirs. A key ingredient is electrical and co-optimization. Generic formula maximum output optimum leg length are obtained. The Curzon-Ahlborn limit at can be rigorously derived when dimensionless figure-of-merit very large for any contact resistances. results differ from cyclic thermodynamic engines, some reasons discussed. also point out similarity differences single-level quantum dot heat which assume no explicit resistance
