Project Apollon cooperates with SolarTec AG

14.11.2008: Project Apollon cooperates with SolarTec AG

SolarTec AG assumes responsible position in technical project coordination:

German photovoltaics company SolarTec AG was elected as industrial partner of the European Photovoltaics Project APOLLON (Multi-APrOach for high Efficiency integrated and inteLLigent cONcentrating PV modules/systems). APOLLON, a cooperation of European photovoltaic research institutions, aims at the development of high efficiency concentrator technology, focussing on innovative photovoltaic systems in the field of “PF -Point Focus” and “High Density-Mirror Based Spectra Splitting.”

SolarTec AG won recognition against strong competition of more than 400 project applicants, including worldwide renowned research institutes and universities. The total budget of the project amounts to approx. 11.7 Mio. €, of which 8.2 Mio. € will be funded by the EU.

Together with subsidiary company ENE, SolarTec AG is in funds of a 2.1 Mio. € budget (1.6 Mio. € funded by the EU) until 2012. Under the lead of CESI RICERCA (I), and in cooperation with 13 further
renowned companies and institutes from 10 countries, SolarTec AG will develop an innovative concentrator system for competitive, high-efficient photovoltaic electricity generation.

Solar Tec’s most important project partners are:
– CESI RICERCA, Milan, Italy
– AIXTRON, Aachen, Germany
– JRC, Ispra, Italy
– ECN, Petten, Netherlands
– ROBOTIKER ENERGÍA, Zamudia-Bizkaia, Spain
– ENEL, Italy

At the Kick-Off on July 10, 2008 in Milan, Italy, work contents and responsibilities of the project partners were fixed. Amongst others, project focus on in the development of a new, non-imaging
lens (Fresnel and Prismatic lens), combining high concentration and optical performance with wide
acceptance angles.

Another aspect in the research project is the enhancement of micro-solar-cells (multi-junction solarcells) on the basis of III-V semiconductor materials deriving from space technology. Thus the APOLLON project credits with a somehow historic role, aiming at photovoltaic efficiencies beyond 40%. In order to reach that, new materials for MJ (Multi Junction) solar cells will be tested and produced in Solar Tec’s laboratory. During extensive “indoor” and “outdoor” tests, the concentrator-modules are checked on performance, quality and long life durability by reference measurements.

The tracking system is crucial for the efficient use of concentrator technology. SolarTec will develop a novel, intelligent and cost effective system that enables optimal performance of the complete

SolarTec AG commits itself to a responsible position in the technical coordination of the project, as well as in implementing operational results into industrial production and commercialization of concentrator PV-Technology.

Main tasks of SolarTec AG are:
Optimisation of primary lenses
Optimisation of the complete module production process
Long term stability of the modules (with JRC)
Optimisation of cost-effective, highly-precise tracking systems of SolarTec (jointly with ROBOTIKER
Development of secondary lenses
IEC-Certification (with JRC)
Construction of a test installation in Sicily (with ENEL)

ENE’s main tasks will be the development of “multi-layer-cells” with a concentration factor of 1,000 and an effectiveness of more than 35%, as well as the production of Ge-Wafers for the whole consortium.
