Abstract :
Properties of photovoltaics based on intersubband transition have been investigated. Specific structures have been designed to absorb energy efficiently emitted from a black body kept at 1300 K. Fast response has been obtained by reducing the relaxation time of the photo-excited carriers by adjusting the LO phonon scattering rate.
