Perovskite-silicon tandem solar cell based on indium oxide buffer layer achieves 30.04% efficiency

Researchers in China have fabricated a perovskite-silicon tandem solar cell that utilizes an indium oxide sputtering buffer layer to protect the perovskite absorber and the electron transport layer from potential damages arising from the electrode deposition process. The new layer not only ensured this protection but also showed strong optical and electrical properties. Researchers at the Northwestern Polytechnical University in China have fabricated a four-terminal (4T) semi-transparent perovskite-silicon tandem solar cell based on a top perovskite cell integrating an indium oxide (In2O3) sputtering ...
