The role of electrochemical potentials of solid-state energy emissive harvesters

We prove that semiconductor and metallic energy-emissive harvesters, thermoradiative cells and intermediate-band thermoradiative cells are obtained from the concept of core radiative material doing different approximations. We also show that using this concept it is possible to predict new outcomes on energy-emissive harvesters. Among the new results we highlight the possible failure of the particle conservation model if used on cold-carrier energy emissive harvesters, that intermediate band solar cells must produce small output powers and the reduction of the cell power of thermoradiative cells due to multiexcitonic processes. Moreover, we explain the physical principles of the differences found between results obtained using the detailed balance method and results that are obtained without using it.
