Keywords:detailed balance, resonant tunneling diodes

I constructed a new detailed-balance model to find a suitable structure of energy-selective contacts used for hot-carrier solar cells. It has been found that a wide-bandgap layer can achieve a higher conversion efficiency than previously used double-barrier resonant tunneling diodes consisting of semiconductor quantum dots and quantum wells, because of its higher conductance.
