Upscaling and Stability

Objectives

The research on upscaling and stability of perovskite photovoltaic solar cells in CHEOPS was essential for the achievement of the overall project mission. The main target was to develop a better understanding of degradation mechanisms in devices and to establish a measurement and stability testing protocol for perovskite technology.

Achievements

The main developments concerning upscaling and stability in CHEOPS were focused on the following aspects:

  • Determination of the possible degradation mechanisms and definition of measurement and stability testing protocols
  • Development of possible encapsulation processes, starting with rigid encapsulations and then proceeding to flexible encapsulation
  • Determination of the best process conditions leading to stable devices
  • Establishment of process conditions for upscaling

Università degli Studi di Roma ‘Tor Vergata’

The University of Rome “Tor Vergata” is based on a campus of 600 hectares with 43,000 students and 19 Departments. The University has established in 2006 together with the Lazio Region the “Centre for Hybrid and Organic Solar Energy” (CHOSE). The centre’s objectives are the research and development for the industrialization of organic and hybrid organic-inorganic technologies via three main steps: i) define a technological process for organic/hybrid cells, ii) develop fabrication processes for indus-trialization, iii) foster technology transfer towards SMEs. More than 30 researchers including 15 PhDs, 8 Post Docs, 4 Staff Members and other students and technicians are currently working at CHOSE. CHOSE is member of the EERA-PV platform, participates in the GRAPHENE Flagship, and is a partner of Dyepower, a R&D consortium for industrialisation of DSC facades.
