Industry Partner

  • Jinko Solar

Summary

In this project, ANU is working with Jinko Solar to develop new approaches for perovskite-silicon tandem solar cells.  The efficiency of standard silicon solar cells is limited due to the way they absorb light. This project will work to develop innovative, high efficiency solar cells using a combination of perovskite materials and silicon. Using perovskites will allow higher efficiency by making better use of blue light in the solar spectrum. ANU previously achieved a world record efficiency for perovskite-silicon tandems, and together with Jinko Solar will build on this work to produce larger, more efficient and more stable solar cells that have the potential for commercialisation.
