ICFO Physicists Report Solar Cell Design Beating Shockley-Queisser Limit

Barcelona researchers say a new optical-cavity cell architecture could push single-junction solar efficiency from 33.7% toward 43%.

What to know

  • ICFO researchers say they found a way to exceed the Shockley-Queisser limit (33.7%), a single-junction solar cell efficiency ceiling accepted since 1961.
  • The approach redesigns the cell as an optical cavity that reduces photon emission losses, without adding fabrication complexity according to the team.
  • The work is theoretical/experimental; most commercial panels today run below 25% efficiency, so reaching even the old 33% ceiling, let alone 43%, remains rare in practice.

“Achieving higher efficiencies is essential, because they directly translate into a lower cost per watt and more efficient use of land and materials for solar energy deployment.”

    ICFO team reports solar cell design exceeding efficiency ceiling

    A research team led by Professor Jordi Martorell at ICFO in Barcelona describes converting solar cells into an optical cavity that limits photon emission losses, with author Francisco Bernal Texca saying the design could push efficiencies close to 43%, above the 33.7% Shockley-Queisser limit.

    “the simplicity of the cavity cell design does not introduce any additional fabrication complexity, unlike many of the approaches currently being explored to surpass the Shockley–Queisser limit…”
