In this project, ANU will be working with Jinko Solar to develop new approaches for perovskite-silicon tandem solar cells. ANU has recently achieved a world record efficiency for perovskite-silicon tandems, and together with Jinko Solar they will build on this work to produce larger, more efficient and more stable solar cells that have the potential for commercialisation.
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.
Increasing the efficiency of solar cells is crucial to continuing to reduce their cost, because higher efficiency systems require less area for a given output power, and hence less glass and other materials. Standard silicon solar cells have limited potential for further increases in efficiency. Combining silicon with other materials such as perovskites is very promising for achieving cost reductions. Perovskites are particularly exciting because they are a low cost material that can be used to make high efficiency solar cells.
