Paper Abstract

We review our recent work concerning the development of dilute nitride solar cells by molecular beam epitaxy. This epitaxial technology enables a high level of control of the growth conditions and alleviates known issues related to epitaxy of dilute nitrides ultimately enabling to achieve high quality materials suitable for solar cell developments. In particular, we focus on discussing the mechanisms linking the epitaxial and annealing conditions to the operation of dilute nitride solar cells. We also report operation of a single junction dilute nitride solar cell with a short circuit current density as high as ~39 mA/cm2 under 1 sun illumination.
