Development of novel materials, processes and supportive actions




The scientific and technical objectives (STOs) of this project are to develop:


A flexible scribing and printing technology that allows producing a given photovoltaic module according to specific design requirements “on-the-fly”. This flexible interconnection will be applied on the solar foil (i.e. an endless solar cell) with a minimum width of 300 mm and will allow curved solar cells and interconnection patterns with a minimum radius of 10 mm.


Novel materials for the underlying flexible solar cell technology to extend the design related degrees of freedom and to optimize the materials used for integrative solar applications.


Novel materials for satisfying design related requirements on solar module level (the part that is most visible for the beholder). Focus will be laid on materials for the electrical conducting front grid to allow an high design freedom of patterns and color variations, as well as using of different novel encapsulants allowing custom designed optical appearance.


A methodological toolbox to provide design rules for the best solar cell super-structure and module design layout for a given application by using numerical modelling and simulation.


New design oriented applications for decentralized solar power generation ranging from low-power demand to high power applications. The developed technologies will be demonstrated in the following applications: solar charging (cover for tablet PC and solar powered radio), solar powered light,solar powered sensor networks for detection of fire in forest, urbal solar lighting (compact solarstreet lighting system) for Product Integrated Photovoltaics (PIPV), building skins with geodesiccurvatures or other related forms for Building Integrated Photovoltaics (BIPV) and integration ofPV in textile support.


Apart from the research and development of the core technologies itself monitoring and validation will enhance performance and reliability of the solar integrated products. Since design-driven solar products are often operated in subpar angles to the sun and without any back ventilation, solar cell efficiencies will not only be optimized in respect to standard tests conditions but also to the specific conditions of solar integrated solutions.
