Next generation solar cells are based on a family of thin film materials. Specifically, perovskite solar cells have demonstrated meteoric improvements in cell power conversion efficiencies, while simultaneously being easy to fabricate. These developments combine with the intensifying interest in renewables and carbon-neutral energy sources to push perovskite solar cells as a prime candidate for widespread adoption.

Our Innovation

  • The research group developed a technique to screen-print a multilayer architecture of perovskite solar cells.
  • The cells can be fabricated on rigid or flexible substrates.
  • The architecture can be adapted to high through-put methods for large area and large scale fabrication.
  • The architecture is agnostic to specific perovskite formulations and therefore eliminates concerns of short-term obsolescence.
  • Large-area demonstrator cells are obtainable with low capital investment.

There are multiple applications where existing silicon-based solar cells are unsuitable, whereas thin film perovskite cells can meet this latent demand. These uses span building-incorporated photovoltaics (BIPV) and off-grid uses. Estimates are that the BIPV market will reach $23B USD by 2024. In addition there is an early opportunity to construct tandem solar cells, which combines standard silicon PV with a perovskite thin film top layer that harvests energy outside the silicon absorption spectrum.

This specific technology dramatically reduces the required capital to obtain a large-scale proof of concept.
