The objectives of the CHEETAH project are threefold:

  • Developing new concepts and technologies for wafer-based crystalline silicon PV (modules with ultrathin cells), thin-film PV (advanced light management) and organic PV (very low-cost barriers), resulting in (strongly) reduced cost of environmentally benign/abundant/non-toxic materials and increased module performance.
  • Fostering long-term European cooperation in the PV R&D sector, by sharing knowledge, organizing workshops, exchange and training researchers inside and outside Europe, efficient use of infrastructures, promoting best practices and standards
  • • Accelerating the implementation of innovative technologies in the PV industry, by a strong involvement of SolarPower Europe and EIT-KIC InnoEnergy in this program


Coordination activities

Fostering the use of existing facilities and expertise

  • Identify currently running technical-scientific needs
  • Taking profit from the strength owned by each CHEETAH partner

Mobility, education and International Cooperation Activities

  • Coordinate the R&D efforts on an international level
  • Increase level of awareness of scientists for better implementation of PV projects

Dissemination, internal and external communication

  • Provide information to all partners about scientific platforms to present results
  • Ensure that community is informed about project results

Acceleration of innovations’ implementation

  • Boost and efficiently enhance the transfer of knowledge to the industry sector and to important PV market stakeholders and decision makers

Joint research activities

Ultrathin wafer development

  • Produce ultrathin wafers of below 50 micron thickness
  • Suitable for solar cell efficiencies >20%

Cell processing of ultrathin wafers

  • Develop process for solar cells with 23.5% efficiency, 2 gram Si/Wp and <0.3€/Wp

Module development for ultrathin x-Si cells and thin-films

  • Demonstrate 22% efficiency for ulta-thin x-Si wafer-based modules
  • Development of new interconnections schemes and encapsulations for thin-film modules

Advanced light management for thin-film PV

  • Implementation of novel 3D architectures into the process chain of thin-film solar cells
  • Cost reduction per Wp by 20%

Very low-cost OPV

  • Development of an encapsulation-less organic solar cell
  • Screening of materials and layers combinations for enhanced stability
