MULTIJUNCTION SOLAR CELLS

Commercially manufactured single junction silicon solar cells are quickly approaching the maximum PCE reached in laboratories. By stacking absorber layers of decreasing band gap on top of a silicon substrate to form a multijunction cell, a new theoretical PCE limit can be attained. Our team is looking to leverage UNSW's long standing expertise with silicon to integrate III-V semi-conductor compounds and other materials into these multijunction cells. This is an exciting area of research with multiple avenues to innovate and push the design of silicon based solar cells to bigger heights. These range from attempting to lower the amount of silicon needed as a substrate, to searching for novel materials to insolate the cell at the back contact.

The main multijunction topics currently covered are: 

• Perovskite - Silicon Cells

• Chalcogenide - Silicon Cells

• III - V Compound - Silicon Cells
