APOLLON: the Large Integrated European Project of FP7 on Concentrating Photovoltaic, target objectives on technology and costs

Next generation concentrating photovoltaic technologies if used economically will have a large-scale impact on world electricity production. To reach this scope, a new large integrated project, APOLLON, has started in July 2008, within the frame of the 7th European Framework program, to substantially decrease the CPV technology cost to a target value of 2 Euro/W.

This ambitious objective is targeted to be reached after five years of research and technological activities which will be implemented by sixteen partners having the mixture of expertise necessary to face all the technology-critical issues related to each component of the CPV system. So far, APOLLON is the largest integrated project on PV field of FP7. In the APOLLON project new ideas on improving the MOCVD technology will be pursued to growth discrete and monolithic MJ cells, adopting new 1 eV materials, based on epitaxial germanium alloys, possibly capable of replacing the N-containing materials (like InGaNAs). Optimisation of Fresnel and prismatic lenses along with the development of new non-imaging, low F/#, high concentration, cell self-protecting stable optics will be implemented. New concepts will be applied for mirror based spectra splitting systems to eliminate active cooling needs. High integration obtained with microelectronic and automotive light technologies for high throughput module assembly techniques, along with intelligent solutions for accurate, reliable, tracking will be pursued. With this contribution all the target objectives of the project will be reviewed and the path toward a cost reduction will be traced.
