摘要
In this work a new thermophotovoltaic converter is investigated. Strained narrow band gap InxGa1-xAs/In0.47Ga0.53As (x>0.6) multiple quantum wells (MQW) are introduced within the intrinsic region of a conventional In0.47Ga0.53As p-i-n cell lattice matched to InP. An appropriate choice of well/barrier thickness and number of wells in the i-region maintains the pseudomorphism and lattice matching to InP, while, the presence of narrow band gap wells extends photon absorption up to that of confined energy states in wells. For a low temperature black body emitters (1200-1500K) this new device conversion efficiency is predicted to exceed twice that of its conventional counterpart.
