Colloidal quantum dot solar cells on silicon solar cells: Ultra-high efficiency silicon tandems. This project aims to produce ultra-high efficiency solar cells using nanoparticle colloids. Wide bandgap cells will be fabricated and applied on top of the high efficiency silicon solar cells pioneered at The University of New South Wales. Colloidal nanoparticles offer tunable electronic bandgaps, low process temperatures and uniform size dispersions from industrially feasible processes.

This project aims to produce ultra-high efficiency solar cells using nanoparticle colloids. Wide bandgap cells will be fabricated and applied on top of the high efficiency silicon solar cells pioneered at The University of New South Wales. Colloidal nanoparticles offer tunable electronic bandgaps, low process temperatures and uniform size dispersions from industrially feasible processes. A simple modification eliminates direct series connections between stacked nanoparticle solar cells, greatly improving device performance. The immense potential of these advantages set target efficiencies for combined colloidal nanoparticle and high efficiency silicon tandem cells above 30 per cent.Read moreRead less
