Project Title: " Development of low concentration photovoltaic systems with high efficiency solar cells and single axis trackers: Theseus".

Funds: National Programme for Research aimed at the Challenges of Society organized by the Ministry of Economy and Competitiveness, 2014.

Project file number: RTC-2014-2304-3

Recipient: Abengoa Solar New Technologies SA

Project consortium: Abengoa Solar New Technologies, Rioglass Solar, [...] Institute of Concentration Photovoltaic Systems (ISFOC), University of Cádiz and Technical University of Madrid.

Project duration: 2014-2017

DESCRIPTION: ISFOC participates in Theseus Project whose main goal is to develop low-concentration photovoltaic technology for utility scale solar plants and which can compete with conventional flat panel systems in areas with high irradiation. Thus, the following specific objectives will be pursued in order to achieve this goal:

  • Developing new single-axis tracking systems to minimize the cost.
  • Developing high efficiency cells optimized to work in low concentration, taking into account technologies based in monocrystalline silicon and analyzing the potential of III-V technology.
  • Defining and validating a design for the low concentration receiver.
  • Developing new materials for the sunlight selective filtering in order to remove the solar spectrum that is not used with the aim of reducing significantly the operation temperature, thereby increasing the efficiency.
  • Designing new heat dissipation systems to maximize the system thermal performance and reduce both the production and material costs.

To conclude, the results will be materialized in several prototypes which will be used to validate the developed technology. It is in this activity where ISFOC participates, leading the work package where accelerating aging tests are carried out to validate the design according to the IEC62108 Standard “Concentrator photovoltaic (CPV) modules and assemblies - Design qualification and type approval”.

The project is part of the National Programme for Research aimed at the Challenges of Society organized by the Ministry of Economy and Competitiveness. One of the major challenges of the Society is the development of clean, secure and efficient energy. And it is here that this project applies to, raising the development of a low-concentration photovoltaic system which proves competitive in areas with high irradiation against both conventional flat panel systems and generation sources based on fossil fuels. Therefore, this project is clearly focused on one of the most relevant goals defined in Horizon2020: achieving that renewable energies supply more than 20% of the electricity market.
