Valais Perovskite Solar logo imageValais Perovskite Solar (VPS) is a Switzerland-based company with a focus on molecular engineering of functional materials for PV and light-emitting applications.

VPS mainly focuses on:

  • Molecular Engineering of Sensitizers for Dye-Sensitized Solar Cells and Organic Light-Emitting Diodes
  • Perovskite solar cells
  • Design and development of charge transporting materials
  • Photophysics and Photochemistry of Molecular Assemblies

The goal of VPS is, according to its website: "to engineer at the molecular level novel panchromatic sensitizers and functionalized hole-transporting materials to achieve power conversion efficiency (PCE) surpassing 23%. Because many chemical combinations result in a perovskite crystal structure, and each of them has different optical properties, choosing the chemistry of a cell also means choosing what part of the spectrum it absorbs, this could push efficiency levels in the future up to around 36%. It may be possible to manufacture also a panel that is 30% efficient using standard solar cells in combination with perovskites".
