Abstract

Herein, we present a quantum well (QW) structure design for the intrinsic region of p-i-n solar cells to extend the absorption of incident photon flux. The structure parameters to achieve suitable level positions for the suggested p-i-n junction have been calculated theoretically by solving the Schrödinger equation. A GaAs/Al0.3Ga0.7As triple quantum well with the theoretically calculated structure parameters has been grown by molecular beam epitaxy. The photoluminescence measurements on the fabricated structure show the emission from the corresponding QWs. Further experiments are underway to understand the possible tunneling of photo-generated carriers through the wells.
