"no need for 1 side hot/ other side cool... lower cost, higher energy efficiency, no need for hazardous radioisotope thermoelectric generators... many organic compounds easily transfer energy between each other (electron charge transfer interfaces): 180 nm copper phthalocyanine layer, 180 nm copper hexadecafluoro phthalocyanine layer... also, 20 nm each of fullerenes and bathocuproine, facilitating electron transport,,, . open-circuit 384 mV, short-circuit current density 1.1 μA/cm2, maximum output 94 nW/cm2"
