An international team of researchers has built the first high-performance, commercial-size tandem solar cell that doesn't rely on the scarce and expensive metal indium. The breakthrough, published in Science, replaces indium-based oxide with abundant tin oxide, a material that costs 1% as much, without sacrificing performance.

Researchers have developed an indium-free perovskite-silicon tandem solar cell using a low-damage reactive plasma deposition process to produce tin oxide layers, achieving…
