This research project seeks to develop innovative solar energy to support water treatment in remote and low resource settings.
This project will address an important challenge within the IC-IMPACTS strategic area of Integrated Water Management through the creation of a renewable energy source that can deliver the power needed for potable water treatment in remote settings at low cost. Off-grid power is a critical factor in enabling water treatment in remote and low resource settings where a dependable electricity supply is often hard to find – applicable to communities in both India and rural Canada. However, such power is one of the main contributors to the cost of water treatment.
Colloidal quantum dots (CQDs) are semiconductor nanoparticles synthesized in, and processed from, the solution phase. Solution processing enables low cost, high throughput manufacturing onto flexible substrates using spray or slot-die coating with roll-to-roll printing. We have demonstrated the first tandem quantum dot solar cell based on a multiple absorbing layers of tuned quantum dots (Wang et al., Nature Photonics, 2011) and have driven efficiencies up to 7% certified externally (Ip et al., Nature Nanotechnology, 2012).
We will leverage these advances to scale up our solar cell technology for in-field demonstration with a water treatment system through IC-IMPACTS. In collaboration with the Integrated Water Management team, and partner communities in India and Canada, we will build, test and demonstrate the viability of our solar technology for off-grid power.
