摘要:
Electroluminescence coupling between the wells in multiple quantum well (MQW) structures is taken into account to show how, if the emissivity of one well equals its absorptivity, then, the emissivity of the whole structure also equals its absorptivity. This result is used to critically analyze previously reported results in which the limiting efficiency of MQW solar cells were supposed to exceed the limiting efficiency of single bandgap solar cells.
