Tandem ART

Tandem ART has developed a low-cost solution to fabricate tandem solar cells by integrating Si wafer cells with thin film cells. Our novel method transforms common insulating polymers into conductive polymers, which can then be used to bond subcells together to produce tandem cells. The technology removes constraints on subcell compatibility and significantly simplifies tandem cell fabrication, paving the way for accelerated commercialisation.

Tandem ART members have strong expertise in PV materials and device development. Inventors include Scientia Professor Xiaojing Hao (FTSE, FAAE) and Scientia Professor Martin Green (FTSE, FAAE).

• High-efficiency tandem solar cells are recognised as the next generation of solar PV products, since current Si solar cells are approaching their theoretical efficiency limit.
• This in-demand tandem cell is not yet available on the market due to incompatibility and the difficulty of integrating subcells.

• Initially, PV rooftop/building-integrated/vehicle-integrated PV system distributors, who require high PV power output in a limited area
• In the long term, all kinds of PV power plant developers will benefit from further cost reduction of this tandem cell product

• Awarded an Australia Economic Accelerator (AEA) seed grant by the Department of Education
• Successfully demonstrated prototype of tandem solar cells
