In this work, we report theoretical and experimental results on the use of Cadmium Telluride (CdTe) doped with Zinc (Zn) as core material for the development of all-optical photonic devices. We include the design of optical waveguides for strong field confinement, technological processes to grow CdTe on 6” or 8” wafers (suitable for high-volume manufacturing) as well as the fabrication and opti...

Ultrafast exciton dynamics in 2D in-plane hetero-nanostructures: delocalization and charge transfer.
In this article we study the ultrafast dynamics of excitons and charge carriers photogenerated in two-dimensional in-plane heterostructures, namely, CdSe-CdTe nanoplatelets. We combine transient absorption and two-dimensional electronic spectroscopy to study charge transfer and delocalization from a few tens of femtoseconds to several nanoseconds. In contrast with spherical nanocrystals, the re...

Roll-to-roll manufacturing of CdTe solar cells on flexible metal foil substrates is one of the most attractive options for low-cost photovoltaic module production. However, various efforts to grow CdTe solar cells on metal foil have resulted in low efficiencies. This is caused by the fact that the conventional device structure must be inverted, which imposes severe restrictions on device proces...
