Thin Film light-trapping enhanced Quantum Dot photovoltaic cells: an enabling technology for high power-to-weight ratio space solar arrays (TFQD)<\/strong><\/h2>\n

With TFQD we aim at developing a new generation of high-efficiency thin-film photovoltaic devices for future solar arrays, by exploiting cross-cutting Key Enabling Technologies<\/em> as: advanced manufacturing, advanced materials, photonics. The core device is a thin-film III-V solar cell embedding quantum dots and nanophotonic gratings to boost the efficiency beyond the thermodynamic limit of conventional single-junction devices. Combining the thin-film approach with the nanostructuring of semiconductor layers allows for a drastic improvement of power-to-weight ratio<\/em> and mechanical flexibility<\/em> with respect to currently available space solar cells.\u00a0 The incorporation of quantum dots provides improved radiation and temperature hardness.<\/p>\n

The TFQD device targets efficiency higher than 26%<\/em>\u00a0AM0 (30% AM1.5G), at least an eight-fold increase of power-to-weight ratio vs. triple junction III-V solar cells and very low bending radius, allowing for the development of rollable or inflatable solar arrays.<\/p>\n

Demonstration up to TRL4 will be carried out through on ground testing under representative in orbit<\/em> conditions over a set of 44 prototypes of area of 1 cm^2.<\/p>\n

The consortium includes four academic partners<\/em> having a strong position in modelling, epilayer growth and development and manufacturing of thin-film III-V solar cells, a SME<\/em> able to quickly implement the new technology in their thin-film solar cell production line, and a company<\/em> that is a European leader in satellite systems as early adopter of the developed devices to boost innovation in space solar panels.<\/p>\n

On account of wafer reuse and simplicity of the epitaxial structures, the TFQD solar cells are less expensive than the current state-of-the-art multi-junction solar cells, thus also important impact potential on terrestrial applications, as first in concentrating photovoltaic systems, is foreseen.<\/p>\n
