Influence of different electron and holes effective masses, temperatures and electrochemical potentials on the hot carrier solar cell efficiency

Third generation hot carrier solar cells could achieve very high conversion yield at reasonable cost. Different theoretical approaches have been used to model these devices and to determine the maximal achivable efficiency, by taking into account different working conditions as well as different losses. However, the uncertainty about the kind of the carrier which heats has led to consider in the different models that both electrons and holes were at a same hot temperature. Here we revisit the theoretical work about hot carriers in order to take into account two different hot temperatures, one for each type of carrier (electron or hole). Then we use this theoretical approach to model the hot carrier solar cell performance with different electron and hole thermodynamical properties.
