Organic and Perovskite

Solar Cells

The development and fabrication of high-efficiency semi-transparent organic and tandem solar cells for window and commercial applications . This includes device structure design of tandem devices to improve the device efficiency toward a theoretical efficiency of 40 percent .

Competitive Advantage

• Unique expertise in developing semi-transparent organic solar cells of 12 % efficiency , with average visible transmittance ( AVT ) of 25 % for window applications
• World-class facilities for characterisation of organic and perovskite semiconductor materials and for the fabrication of OPV and perovskite solar cells

Impact

• Organic and perovskite photovoltaics differ from crystalline solar cells – they can be produced with affordable solution-based manufacturing processes , and designed to be lightweight and mechanically flexible ( for vehicle and architectural integration )
• UNSW has developed solution-based processes for tandem fabrication that can significantly reduce the cost of production for semi-transparent organic and tandem solar cells

Capabilities and Facilities

• Development pipeline of new materials and devices for organic and perovskite materials
• Facilities for organic and perovskite materials and devices fabrication and characterisation ( TEM , SEM , AFM , XRD and XPS , and micro-Raman )
• Advanced optical / spectroscopy capability for spectral measurements , including absorption , PL , and FTIR

Our Collaborators

• Huawei – transparent organic photovoltaic devices
• Dyesol
• Future Solar
