The team at ANU has been working on novel Interdigitated Back Contact (IBC) cell technology to improve solar cell efficiency and provide a roadmap to commercial adaptation of the technology.
Report extract
IBC cell design stands out as one of the more refined device designs for single-junction Si solar cell.
ANU has demonstrated IBC cell efficiencies of 25%, however, the technology faces challenges due to complexity of IBC patterning which results in poor cost-performance ratio.
This report provides an insight of ANU’s innovative hybrid-IBC Si solar cell designs and preliminary results from their prototype. These results, combined with device simulation offered a technology roadmap for upscaling for IBC technologies.
The report details the process, experiences and learnings from the project including:
- Technical details of the Hybrid-IBC Si solar cell
- Simulation of the device and technology roadmap
- Challenges and Pathways toward industrialisation of the technology.
