Luminescence-based imaging system for industrial tandem solar cells. This project aims to develop an Australian-made inspection system for next-generation solar cells. Besides allowing, for the first time, fast measurements of large-size tandem solar cells, the system will also enable the determination of key parameters that cannot be measured by current methods. This capability is expected to generate new knowledge in the areas of perovskite and tandem solar cells.

This project aims to develop a new defect-control approach for silicon-germanium heteroepitaxial semiconductor systems to provide a route for high-throughput, low-cost, high-efficiency silicon tandem solar cells. Mismatched heteroepitaxy of semiconductors is of considerable interest for fabricating novel devices. However, the use of highly-mismatched heteroepitaxial semiconductors has been limited due to the high densities of crystal defects which degrade the performance of both majority and minority carrier devices. This project aims to develop a new defect-control approach for heteroepitaxial semiconductors by continuous wavelength diode laser processing. With heteroepitaxial silicon-germanium as an example, the project will investigate the mechanism underlying defect-cleaning, optimised designs for best performance, and designs for high-efficiency tandem solar cells.Read moreRead less
