Photothermoelectric converter: A new design concept

A new concept of the photothermoelectric converter (PTEC) is proposed, which is free of the main disadvantages (overheating of the photocell and insufficient heat flux in the thermocell) of the existing schemes. The problems are solved using a PTEC scheme with a narrowband optical filter, which transmits radiation with the optimum spectrum to the photocells and directs optimum heat flux to the thermocell.
