Solar PV R&DProject Advanced Silicon Solar Cells
This is the final report for the Advanced Silicon Solar Cells by DESIJN (Deposited Silicon Junctions) project.
The project has focussed on the development and deployment of a new silicon solar cell technology in collaboration with our industry partner Jinko Solar, one of the top three PV manufacturers globally. Specifically, we have developed industrial processes for the fabrication of high efficiency n-type silicon solar cells using phosphorus-doped poly-silicon passivating contacts on the rear side of the device (sometimes referred to as TOPCon cells). This has led to several world record large-area cells made with this new technology, including most recently a 25.25% efficient solar cell fabricated in the pilot lines at Jinko Solar, with screen-printed metallisation and industrially-compatible processing. Jinko Solar intend to move this technology to mass production in the near future.
