CMC Microsystem growth funding awards for SUNLAB!

SUNLAB has been granted funding from Canadian Microelectonics Corporation (CMC) to develop a four-junction solar cell using InGaAsN(Sb) dilute nitride material. This project builds on previous work with single-junction dilute nitride solar cells. The first stage of the project has been completed, yielding a series of wafer templates with germanium bottom sub-cells and epitaxially grown tunnel junctions, which will form the basis for growth of complete four-junction devices.
