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, [...] Instituto de Sistemas Fotovoltaicos de Concentración (ISFOC), University of Cádiz and Technical University of Madrid.

Project duration: 2014-2017

DESCRIPTION: ISFOC participates in Theseus Project, with the main goal of developing low-concentration photovoltaic technology for industrial-scale solar plants, 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 costs.
  • Developing high-efficiency cells optimized to work in low concentrations, taking into account technologies based on monocrystalline silicon and analysing the potential of III-V technology.
  • Defining and validating a design for the low concentration receiver.
  • Developing new materials for sunlight selective filtering in order to remove the solar spectrum that is not used with the aim of significantly reducing the operation temperature, thereby increasing efficiency.
  • Designing new heat dissipation systems to maximize the system’s thermal performance and reduce both the production and material costs.

In conclusion, the results will be materialized in several prototypes, which will be used to validate the developed technology. ISFOC participates in this activity by leading the work package where accelerated aging tests are carried out to validate the design according to the IEC62108 Standard “Concentration 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, safe, and efficient energy. This is how the project is applied, raising the development of a low-concentration photovoltaic system that 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: having renewable energies supply more than 20% of the electricity market.
