following specific objectives have been
defined for the project:

•	 Development of a novel wafer
    bonded four-junction solar cell
    for better spectral matching with an
    efficiency of 48% using advanced
    materials and processes

•	 Development of a lattice-matched         Wafer with multi-junction concentrator solar cells © Fraunhofer ISE
    multi-junction solar cell with high
    efficiency potential and low process
    cost, comprising nanostructured
    coatings and innovative lattice-
    matched materials, obtained by
    combing III-V and IV elements

•	 Development of innovative, Fresnel
    lens-based HCPV modules

•	 Development of smart, mirror-based
    HCPV modules

•	 Life-cycle and environmental
    assessment of new multi-junction
    cells and HCPV modules

•	 Assess the developments realized on
    solar cells and modules by means of
    adapted characterization methods
